When I look at people I don't judge by the way the dress or the
color of their hair or whatnot. I judge the way they observe
their surroundings, the way they look at people, the way they
talk to others, and the way they hold themselves. That's what you
look for to find out about someone without ever speaking to them.
You see how friendly they are, you see how they view people, you
see how alert and experienced they are, and you see how they
think of themselves.
