So I was in a meeting earlier with the door closed. I was at my desk and my principal and two teachers were sitting in chairs across from me. Anyway, a teacher barges in, looks around, and asks, "Oh, are you busy right now?" I literally paused, looked around, and said, "Yes, (insert first name), I am indeed very busy right now." I would never walk into someone's office when their door is closed. There's a large window in my office door, so she could've clearly seen I was in a meeting. End of rant. Thank you.
