Seriously, I'm very blessed to have an office, it's more privacy than I've ever had, but it's a glass door actually and I think people think that I may as well not even have one sometimes...some are more respectful than others. I try to leave my door open at all times unless I absolutely have to, so you'd think that if the door was closed people would get the idea...but I swear it's like to those few, a knock knock and a wave is all that is needed to just barge in. And it's usually something that could wait.
