Even adding a little drama to the none that I currently have is annoying...

Postdoc is either:
1) A nice guy who thinks its appropriate to want to have lunch with me as a coworker.
2) A little dense and wants to have lunch with me even though I talk about my boyfriend. Who I'm living with. Soon to be living with without an additional roommate.

I hope it's #1. I also hope that in his mind this is a one-time, get-to-know-you kind of thing, because I don't do staged coworker lunches all too often. Too awkward. Especially if it's just me and one other person! Maybe he got the idea from the boss, who took him to a restaurant last week... ugh... another notch in the "dislike" section.
