Driving.

The drive between our parents' houses and our own house is about ninety minutes, and though she usually tries her best, Tamsen often falls asleep on the drive. (Not that I blame her. I'd fall asleep too, if I weren't driving.) She fell asleep on the drive home last night, and at one point, I felt a gentle poking on my arm. I looked over and asked her, "Hey, what are you doing?"

"Oh!" she said, clearly still asleep. "I thought you were a pillow."
