Some of the time I’m over at the desk to check people onto computers. This involves you walking up and scanning a library card or showing identification. In this exchange, you tell me who you are and I give you a computer that is numbered; there are about four opportunities, if all goes well, for us to talk. When you walk up. When I say hello after you have walked up. When I tell you the number of the computer. When you walk away. But some appear and never say a word, never answer back. The down look down because something weighs. To look straight ahead would mean allowing something or someone –me—to show up in between.
