follow people’s feet, hands and shoulders. most people show intent with how they move those parts of their bodies. if you “study” people long enough you can sort of learn what someone will do before they get close enough to you that they can affect you (e.g. get in your way, put their hands on you, etc). don’t bother with faces, I think that’s the biggest mistake people make – they try to draw something from the persons eyes, facial expressions or what they say, but those are all just illusions, it’s irrelevant shit that is just meant to distract you. without them moving their feet, shoulders and hands, they really can’t hurt you…unless you meet like a wizard or something I guess
