talk too much
There are times when my friend talks to herself. She says that she's had this conversation with me before, and she knows that she hasn't talked with me, but she wanted to talk to me, so she talked to herself as though she was talking to me. She does this when she's alone. Is it normal?
But what your friend does, is one step too far :P
Me thinks you two are so close to each other just like sisters and as a bestfriend it should be your business to tell her wat you think. Doing it in private's ok but in public....that's just plain weird and dat's putting it mildly. I hope you tell her about it
