This whole thing is spot on! There was a girl I went to college with who would mouth my words as I said them. Imagine talking and someone is silently repeating what you say. And the minute I stopped talking, she would launch off into something that had nothing to do with what I was talking about. Needless to say, I avoided talking to her quite a bit. Worst part, she was my assigned mentor when I got to college and would blow up my phone to go shopping with her. Ack!
