i walk slowly. my sister actually commented on it recently.. we were walking somewhere together and she kept finding herself getting ahead of me. she said it made her notice how fast she walks. i just let her walk fast, its whatever. she can slow down if she wants to walk with me. same goes for anyone else. as far as keeping your head up, hands in or out of pockets, whatever.. just make sure that you arent slouching. nothing wrong with looking at the ground if youre about to go over a curb or something, but for the most part keep your head up and your chin up. chest out. swing your arms slow, deliberate steps. the general idea is to let everyone know by the way you walk that if they fuck with you, theyre gona have a fuckin problem. thats how it is where i grew up anyway
