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.
