Then one day, as I was driving, a squirrel got caught in the middle of the road in front of me, not knowing whether to stay put or run. I swerved to miss it, but instead I hit and killed it. I felt awful. I don't think I'd ever killed anything larger than an insect before. Except a snake.

I kept thinking afterwards that if I'd just kept going straight, the squirrel would have figured it out, what to do. By changing course, I had run into his plan for escape.

Don't swerve is my new motto.
