Not having been there, I can't really know her intentions, but it actually sounded to me like she was trying to start a conversation with you. Maybe that was the only thing she had heard about you, so that's all she could start with. Besides, think about it, she had talked with someone else about you, then approached you on her own. That sounds like interest to me.

Again, I wasn't there, but it sounds like you made a generalization about her when complaining about what you felt was a generalization about you.
