"Again? But she's great for you."

"I have trouble holding on to great women."

"Don't I know it."

Jenna, my lovely ex, has been remarried for eight years. Her new husband is a well-respected surgeon named Noel Wheeler. Noel does volunteer work for me at the teen center. I like Noel and he likes me. He has a daughter by a previous marriage, and he and Jenna have a six-year-old girl named Kari. I'm Kari's godfather, and both kids call me Uncle Dan. I'm the family go-to babysitter.

I know this all sounds very civilized and Pollyanna, and I suppose it is. In my case, it could be simply a matter of necessity. I have no one else-no parents, no siblings-ergo, the closest thing I have to family is my ex-wife. The kids I work with, the ones I advocate for and try to help and defend, are my life, and in the end I'm not sure I do the slightest bit of good.

Jenna said, "Earth to Dan?"

"I'll be there," I said to her.

"Six thirty. You're the best."

Jenna made a smooching noise into the mouthpiece and hung up. I looked at the phone for a moment, remembered our own wedding day. It was a mistake for me to get married. It is a mistake for me to get too close to people, and yet I can't help it. Someone cue the violins so I can wax philosophical about how it is better to have loved and lost than to never have loved at all. I don't think that applies to me. It is in humans' DNA to repeat the same mistakes, even after we know better. So here I am, the poor orphan who scraped his way up to the top of his class at an elite Ivy League school but never really scraped off who he was. Corny, but I want someone in my life. Alas, that is not my destiny. I am a loner who isn't meant to be alone.

"We are evolution's garbage, Dan…"

My favorite foster "dad" taught me that. He was a college professor who loved to get into philosophical debates.

"Think about it, Dan. Throughout mankind, the strongest and brightest did what? They fought in wars.
