There are 2 kinds of employees here. The first keep their doors close all the time. The second, keep their doors open. I belong to the latter - because, after all, I am paid to be available. But sometimes, I like to shut the door and seal myself in that vacuous space where time is suspended until it's time to go home.
Sometimes I wonder what the folks who keep their door shut do all day. Sometimes I don't see them for weeks. It's almost like that Friends episode where Jason Alexander plays this suicidal office worker who goes unnoticed in the middle of a busy office. Or it's like the urban legend account of this office drone who is discovered at his desk years after he has passed away.
