A boring job

You stand at the door all day, every day, even weekends. How long ago was it you were told to guard this vault? You can't remember. You wish you'd thought to start marking the days in chalk on the wall when you started, but you didn't. You could start now, but what's the point?

An interminable amount of time passes. You think about leaving. Nothing is going to happen without you.

Leave your post.

Stay and wait. You made a commitment, after all.
