People I get nervous around... wow, there are quite a few XD I'll give you my top 3.
1. Friend of a friend. I think everyone gets nervous around these people but I don't just get nervous but awkward too. I try to make a good impression but I know nothing about them except what them and my friend have in common (which usually isn't something we have in common).
2. Large groups. I don't like to get up in front of people but large groups freak me out and I get nervous as crazy before having to do anything.
3. Job interviewers. No joke, I get full on nervousness when I'm getting interviewed even though I have nothing to be nervous about (I have no criminal record and have never gotten into trouble, not even a speeding ticket or warning). Interviews just make me nervous XD
