it's part respect and part intimidation.
witch is good sometimes.
you see when I started liftin @ 19 I wanted too look like an underwear model to attract the girls, now I'm 38 and a taxi driver/doorman
I want to look scary, put people off robbing me. but I can also be very nice to people and smile a lot, like the other guy said.
someone wanted to give me a job in a rough part of town, as a bar manager,witch I have done before, he wants someone who looks scary, but who can be a nice guy and hold an intelligent conversation. MY friend said to this guy, " he looks like he eats babies, but I have not yet seen him do it"
looking a certain way and acting that way are two different things.
just remember what you are on, and how it may make you act.
