As people, we're generally optimistic, no matter how disabled our lives are, and we find the humor in the darkest situations.

I grew up in a family that was very barbed and difficult, and there was a lot of humor. None of it was painless humor. All of it was at someone else's expense. It was kind of always about power.

Both of our children are adopted, and my wife and I didn't go out of ways to find kids that looked like us. We were just happy to have some kids. And people tell me all the time that they look like us, and that's because they learn to smile and laugh and move their head a certain way from studying their parents' faces.
