It happened tonight at the gym. It happens all the time when I’m working with high school students, having drinks at bar, walking my dog, watching television.

I feel a tiny wince somewhere in my chest, I wish I was that young. I’d like a do over or a do it all again.

This doesn’t last long. I don’t have the option of wallowing when I’m raising a twelve pound weight over my head, explaining the difference between subsidized and unsubsidized loans to a seventeen year old, or hanging out with my friends.

We’re all so busy lately. I’m busy, my friends are busy, everyone at work is losing their minds. Some of my colleagues are eating lunch at their desks, staying long after doors lock and sending emails at 2 am Sunday morning. (Not me. I have lunch with my friends, but that’s a different story, because my friends at work are the best.)

Essentially, I have too much going on to dwell on my age, or whatever the hell age I’d like to be.

Tonight, I dwelled.

When I was in high school, I drank Miller Lite behind the bathroom at the Tourne, a park in my hometown. A lot of people did this, I was known for being Rob’s shadow and spent the first six months of our relationship agreeing with everything Rob said, until we’d been together for a few months.

Around this time, I discovered the excruciating joy of passionate arguments in the middle of the street, in the middle of the night, in the snow, barefoot, because whatever the hell we were fighting was so important it couldn’t wait four hour until he picked me up for school. When I wasn’t whipped up and hysterical about Rob, I used my free time to squabble with my mom about why I had to empty the dishwasher when we had a housecleaner, and walk around a lake called Mountain Lake. I didn’t do any homework or play any sports, but it’s obvious, I was quite busy.

During my twenties, I was sad. My father died when I was twenty-two, and although he’d been sick for a while, his loss hit hard. I wasn’t hospitalized; I went to school, held some jobs, went through the motions, but looking back, I see a sad girl who should have been in therapy.

During my thirties, the first thing my brain tells me to write is I had a damn good time. I was on guest lists, went to concerts in limos, stayed up until dawn playing backgammon, and weirdly enough, talking about high school. I shopped. I hung out at the pool on the roofdeck on the Sheridan. I went to Walden Pond whenever my friend was kind enough to take me, and if she wasn’t up for it, I took a cab out to Concord and made the driver wait until I was finished. (I had a collection of cabdrivers that drove me places and brought me food and alcohol when I didn’t want to leave the house or the liquor stores were closing.)

Most nights, when we were out, I’d leave first, and head back to my apartment to wait for my friends to come over after the bars closed. I don’t like waiting in line for the bathroom and crowds make me uncomfortable. The limos were nice, and the concerts were amazing, but mostly, what I remember is trying to locate the limos after the concerts. That was not fun, and often took a very long time. Backgammon is fun, especially when you’re winning, but Walden and winning backgammon games aren’t enough to redeem a decade that, from this angle, looks pretty shallow.

I had children in my forties. I remember trying to hold slippery Kate up in the sink so I could wash her hair, and almost dropping her, because I turned around to look at the clock. I needed to know how many more minutes until I could put her to bed.

I skipped through parts of Lemony Snicket when I was reading to Colin because I wanted to get back downstairs to some tv show.

I loved taking them to the pool but we didn’t go often because of how long it would take to get them in and out of their swimsuits. And sometimes, while they were swimming, they’d need to pee. It was so inconvenient, those three to six minutes of helping my kids get ready to play in the water.

As they grew older, they started to move in another direction. I’d take them to the park, leave my book and phone behind, and they’d meet their friends. We’d go for a hike, and they’d want to turn around after thirty minutes so we could go for pizza.

By the time they were teenagers, I caught glimpses. I memorized conversations and wrote about them on Facebook, not to brag, but so I’d have records. I drove Katy anywhere she wanted to go, just to have time in the car. I tried to connect with Colin, but he started drifting away around age fourteen. The only time we spoke was when he lost something in the laundry, the only real conversations we had were in the car when we were on the way home from the police station.

Now, Colin is twenty-two and Katy is nineteen. Neither one of them live at home, but we talk. Colin tells me about his new apartment and sends pictures of his food all the time; this is a trend I don’t understand. Katy shares stories about frat parties I’m pretty sure not every parent hears, sends pictures of her new haircut, her new chair, her form in deadlift, and lately, has let me listen while she tries to figure out what she wants to be when she grows up. Right now, archivist, physical therapist assistant, and media consultant are all on the table. She is also considering archaelogy but I guess the prospects for employment are dismal.

My kids are entirely different, but they pick up the phone when I call. Sometimes I have to call twice and then text, but they pick up.

The only do over I’d like is those fleeting moments when they were really small. I’d sit on the floor with Katy and color, instead of leaving her at the coffee table while I sat at kitchen table on my desktop computer. Colin loved playing with tiny plastic animals, I have no idea what he did with tiny plastic animals, but I wish I knew. I wish I didn’t always rush him off the swings, he loved the swings.

I think most parents go back to wishing they’d had just a little more time giving baths and cutting up vegetables. Maybe that’s why so many want grandchildren; I haven’t gotten there yet.

I’m good with where I am now. I live with a pup who thinks going to bed at nine is almost as much fun as eating cookies.

I work, and eat lunch, with people I like, for students who need my help. I don’t spend a fortune on records, (Spotify!). I like to cook.

I wake up without a hangover; I take my time getting ready because I’ve laid my clothes out the night before.

My kids talk to me, and quite often, when I say something, they listen.

Cancel the do-over.

I need to stop time.

I am sitting at the kitchen table, which is a different space this year than last, or the year before. Next to my elbow is an empty water bottle, brought home from boot camp, a tiny miracle, (I’ve left so many behind.)

There is my daughter’s cat, Maurice, who is mad and has been mad since last September when Katy left for college. He is a three legged cat, yet surprising lethal with his single front paw. It is hard not to laugh when he attempts to strike with the limb that isn’t there. Katy says she misses him but she only Facetimes with Colin’s puppy, Nell.

There are bits from Sunday’s paper; my husband and I went to Foxwoods for the night. I still haven’t read the travel section, barely glanced at the magazine section and book reviews. I might not get a chance to pick it up; I will throw it into the recycling before I read it.

It is the beginning of April, and I’ve considered putting springtime placemats down on the scarred wood surface.

How many? Only Sheldon and I live here now and when we see people, mostly, we are out. Two placemats at a table for six might look sad.

Maybe I’ll buy a plant.

There is a box of Kleenex, which needs to go by the bed; it’s allergy season. Some deodorant Colin left behind, which smells like twenty three year old young man trying to impress the world. I’m sure he’s replaced it with something more expensive. I should bring it up to his room, but his room still feels strange; he only left a month ago.

There is the napkin holder, and a mismatched collection of polyester and cotton cloths, patterns and solids, ancient and shiny. There is a candle that sits on top of a trivet, I have tried to dig out the wick, it has only been lit once or twice..

There are my headphones, my shiny, pink Beats. I wear them on hikes and listen to them at a volume that makes my Iphone send me strongly worded texts about hearing loss.

Sometimes, the best, the only thing to do is to slide them over my ears. Find a playlist I haven’t heard in a million years, slip into whatever sneakers I find in the top of the bin, and step outside.. I only bring Nelly, my son’s puppy, because Sophie can’t keep up anymore.

And sometimes, it’s best to leave the headphones behind.

Not in front me, but in the next room, about ten feet away lies Sophie, The Sweetest of Dogs, on the rug. Tonight, I’d like to slip the leash on Sophie’s collar, and let her lead me wherever she wants to go. She moves, or she doesn’t. We might not make it half a block. She might decide to nap on the front stoop as soon we step down the stair. That’s fine too.

Just this morning, we heard from the vet. Sophie was diagnosed with kidney disease three years ago and the doctor told it was a miracle she’s still here.

By the end of week, Sophie won’t be in the next room anymore.

On Saturday morning, I will be sitting at this kitchen table, probably looking the Kleenex and the newspaper, the deodorant, and, maybe, Maurice. I will glance into the next room, to the space where Sophie sits right now.

I’m going to go sit down next to her.
