I will not be offended if you don't talk to me when you walk into my office looking for her and happen to make eye contact with me. I understand that she outranks me and that most people come in to see her not me. I don't mind you just say something, but don't ask me questions about where she is. See above. You have just as good a vantage point of her desk as I do. If you can't see her there, I can't see her there, and she's probably not there. You don't have to ask me if she's there. You also do not have to walk into the center of the room and look at her empty desk and chair from the other side to make sure she's not there. If you can't see her from the front of her desk, you won't be able to see her from the back of it.
Sometimes, people will not ask me where she is but acknowledge her abscence and then look at me expectedly as if I am supposed to fill in the blank. This morning, she has yet to come in. Her boss came in, looked at her desk, cocked his head and furrowed his brow, looked at me, looked at the desk and said "No Officemate today?" I don't know. Maybe she's late. Maybe you need to check your voicemail to see if she called in.
Work hatred is coming on strong. Tuesday is going to suck a lot.
