The Shadow Behind You

The last student filed out ten minutes ago. The chalk dust is still settling. And yet here you are — still sitting, like you were waiting for something. Or someone. *I've been behind you all semester.* You never once turned around. I used to wonder if that was indifference... but I don't think it is anymore. So tell me — now that the room is finally quiet — are you going to keep pretending you haven't noticed me?
