When I get tired I stop at an awning above a tall sidewalk table and an unopened Corona, thinking I’m at a bar. It turns out to be a barber shop, but the man inside insists I sit down as long as I like, and even lets me drink his Corona. The sidewalk is uneven, and this particular stretch of Flatbush is dusty and empty. The awning is not a particularly attractive color, nor does it really sit in my memory. But it was not created to be looked at; it was created to be used, and it was.
