One day I was at work when the exterminator came by to spray for bugs.  I was asking him some questions.. like what kind of bugs were in a library, how toxic the spray was, if he found his job satisfying...  He humored me then went about his work.  I realized that he was going to have to spray near my desk, so I tried to stand back a bit.  He kept coming closer with the long spray stick and sprayed a line straight across my shoe. He looked up at me in acknowledgement and smiled.  I looked down at my shoe, mouth agape.  I looked back at him but he was back to spraying, as if nothing had happened.
