When Cecily and I were first dating, we often went out drinking in groups. When I got bored, I'd get up from the table at whatever bar it was and go for a walk. Sometimes I'd go 5 or 6 blocks, enjoying the silence of the night, the moths zooming in crazy arcs around the street lamps. Sometimes I'd play the harmonica to the slow stomping blues that was continually banging against the walls of my head. Then when I'd walk back into the bar, it'd be like I'd just arrived. No matter how long I was gone, the conversation seemed uninterrupted. Usually something about tv show or a band. It was like getting back on the highway after a rest stop: just hit the gas and ease back into your lane. It took about a year into the relationship before I was able to drink in a group without getting itchy to leave. In the end it was easy. I just crawled up into my head and looked out the windows. If you ask if I believe in evolution, this is what I'll say.
