Today I went to pub trivia with some people from a club, and one person there seemed like she absolutely hated me.  Or maybe she was just tired, awkward, whatever.

I feel like I can't make any relationships because people dislike me so much. Of course recognizing when someone dislikes you is a good sign because I don't want to waste my time with them. But now I can't actually tell when people are fine with me. What can I do?
