Okay, here's another thing that bugs me. When they leave, people who enter your office should return the door to the state it was in when they entered. If the door was closed when you came by to ask me something, close it when you leave. It's that simple. This has been done correctly exactly one-third of the time today. I'm not asking people to maintain a complex state machine or even a stack for the state of my door; just a single "was the door opened or closed when I entered?" mental variable is fine. But, apparently this is just too much for people.
