Peter and I are plowing through Season Two of "Friday Night Lights," a TV series about Texas high school football. The latest episode we watched was all about families. Families broken up and breaking up. Families struggling and families making progress. It was about facing up to issues, and working to make things better.

In other words, it was about life.

When the episode ended, it looked as though some things were better. Of course, they will get worse again, or the series would be over. But we felt this episode had a hopeful ending.

Peter and I held each other tight for several minutes before turning off the TV. And for some reason, my eyes filled with tears. Why had we been so moved by this? What chord had it struck?

I have no idea.
