When I was 5 yrs. old I got a pair of white go-go boots that I had been wanting. I was always an extremely quite and shy kid, never wanting to draw attention to me but yet somehow I was always the center of attention without even talking. I rarely said a word and people would literally forget that I was there.
So for Christmas that year I got the boots. We were having a big family get together downstairs where my sisters had fixed up a kinda psychedelic room (hippy years), and there were lots of people there. The music started and I got up and started dancing with the boots on, everyone was going on about how cute I was and laughing, and the more I saw that I was getting that kind of positive feedback the more I got into the dancing. If I had seen just ONE disappointed face I would have just walked away and gave up on it.
I'm still that way today! I pay attention to facial expressions way too much. If I see just one person looking like they may be disapproving then I lose all confidence and slink away....
