Office Hovering

Hey Office Hoverer. You know who you are. You stand by the door hovering while I have a conversation with my colleague. You have something to say to one of us and it must be important because you just stand there waiting while we talk about whatever subject we are talking about. I assume if it wasn't important and timely you'd just go back to your desk and check in later. But you don't, you stick around, hovering. But if it's so important and timely, then why don't you interrupt us and say whatever it is you have to say. It'd be way better than having you hover there.
