One of the little joys of my life is waving to people while driving. I take pride in recognizing other people as they approach, even though many of my friends don't recognize me. The best part of this game is reckoning time. I see one friend on her way to work as I am heading to school; where I see her helps me realize how early or late I am. Today, I was at the stop light in town when I saw her. I think it was she who was running late, not me. Phew.
When we took our field trip to the fair, I watched our bus driver wave to every other bus driver who passed. There's a slight chance that he knew them all, but it's highly unlikely. I think it's like biker culture or trucker culture: you wave because you're part of the same club.
It always come back to belonging I guess. Even when driving.
