Thanks, all. Just to clarify, every time she walked by to remind me about the bagels I simply said "Thanks." I nevery got angry with her. Just sort of noncommital.
This is the same woman who told me I was rude for not eating the gargantuan muffins at the new dean's welcome party, told me there was no such thing as gouda cheese, and that I was a snob for liking opera. She normally doesn't speak to me unless she has to (which is fine with me).
I found out later that only 2 people in the office (Annoying Coworker and one other person) actually ate anything. Like I said, it was our last day before Christmas break and only 6 people were in the office anyway.
