It's impossible to tell what people are thinking just by looking at them. Just like everyone else, I like to keep people guessing... and just like everyone else I'm always trying to figure other people out... even though in the end I really don't care. Nevertheless, I always think about these 2 things I learned as small child:
Subtle Signs of Low Self Esteem
1. small handwriting
2. brushing your teeth on the bottom first, top last
I guess they've never been confirmed by a textbook, but I might just have not read the right textbook. I think it's real... do you?
