Every other moment of the walk is a reminder of the vast experiences waiting to be had. Every person, a window into the many hats we might don. But experience has to be pursued. We have to be thirsty for it. The world moves on and time with it. We can watch it go by, bemoaning our position in the spectacle, but if we want to play alongside its many inhabitants, we have to be fun to play with, we have to love our play mates, and we have to understand the game their playing.
