...who finds utterly annoying when coworkers come up to your desk, look at you and then knock on what seems to be an invisible door and then wait for you to say "Come in."
I wish I could cower behind said invisible door and pretend not to be in like I do when my mom's weird friends came to visit and she wasn't home.
What's even more annoying is when they ask after knocking "Anybody home?"
