So this girl and I (from class) were eating lunch, having a great time. Lots of flirting, etc. Then her friend calls, and tells her "Hey you should come over and eat with us". So 30 min. later her friend shows up. WOW. She was pretty big, but "nice" I guess.

But then her attitude immediately changed. Its like she turned into a different girl right before my eyes. I had no idea what to make of it. She went from being sarcastic and funny to kinda quiet and almost stuck up. I had to leave like 20 minutes later, but we were still on good terms and everything (we're going dancing tomorrow night).

I'm missing something. Can anyone explain this? Did I do something?

I just think she was trying to save face in front of her friend and not look like a slvt that talked to a lot of boys...but then again that' s just my opinion.
