Meh thugs aren't that scary you just got to be street smart if one of them notices you're staring at them just nod your head and say whats up, they usually say whats up back and mind their own business. Just don't show any fear around people, predators pick up on fear and it well draw attention to you, its the way of nature. If you remain confident and just mind your own business people aren't really going to bother you.
I did, but for some reason they like to start crap with random people not even looking in their direction, I remember this middle aged guy got on and they started to have a little name calling.
When their by themselves they don't do anything, but the little punks act all big and bad when theres 3 or 4 of them.
