In the article Porrata states, " she's petting something and dancing a bit". I have never viewed the video and thought she was petting something or dancing. It seems odd to me that so many people who are professionals in the medical field view these actions that way. To me she looks like a nervous girl who is very animated when she speaks and she can simply be explaining what has happened with the lift etc. Yes, I suppose if it looked to me as though she were petting air and dancing in the hall I would think drugs or a mental break but I just don't see it that way at all. Her movements are purposeful, even her back to the wall/elevator door seems intentional and her actions seem very calculated and thought out, mind you spur of the moment thought out but still intentional. she isn't trying to "pet , dance or speak to imaginary people" when she is inside the elevator. If they determine that she had a psychotic break I guess I should start seeing a shrink, because I can see myself acting that way if in an unfamiliar area and I get a bit frightened. They say 1 in 4 people are crazy and if you can't point out the person you know as being the one, then it's you.
