Tonight CartGirl and I spent time on facebook, looking for people. My old girlfriends, her old boyfriends. First loves, last loves, friends and enemies, people like that. Just getting to know more about each other, hanging out together, having fun. Our circles overlap in a few unexpected places, that's for sure.

One of her ex-boyfriends was already on my friends list. That was weird. CartGirl says they parted amicably, so I'm not going to be weird about it the next time I see my friend.

We looked up my ex-wife's kids, who used to be my kids if you use a particular definition and squint a certain way.

I always thought I'd recognize them, if I saw them again. But I was wrong. I looked at pictures of strangers tonight. She looks like a more beautiful version of her mother now, not like the awkward toddler I remember. And he is really tall and old-looking. though the smile is the same.

I think about them every now and then, not too often, though. The appropriate amount, I think. I expect they've had a good life so far. I hope so.
