I lived in a shitty neighborhood until 21. I’m white and a minority there. There was a lot of racism, in and out of school. Other kids would throw rocks and try to be tough guy bullies. I’ve been in a few fights that got broken up by teachers. It’s better than letting yourself be picked on.
At about 15 at a park, some other kid wanted to fight. He hit me in the head before I realized we were fighting and I fell, but he slipped and fell too. I was a wrestler in high school and took his back and put on a (poorly executed) rear naked choke and banged his head against the ground until he gave up. I’ve since done BJJ (I’m a Gracie blue belt) and know how to choke properly. 3-4 seconds and someone can be unconscious.
One time I was meeting friends at Dairy Queen (in Burien near Seattle). My friends were already there. A bunch of kids were hanging around at the door. I tried to go in but one blocked my way (big, but small for a Samoan guy). We talked for a couple minutes, I knew some of the people from his neighborhood (South Park in Seattle, shitty place). Then he said “what set you from?” a few times then punched me in the head. I staggered and he and all his friends ran away. I was left standing very confused.
I’ve never been mugged or in a fight as an adult. Kids are stupid. Once you get away from the stupidity and hopefully from the bad areas, it doesn’t seem to happen much. If you are young and this shit happens to you a lot, just persevere and know that it isn’t always going to be like that.
Talking about avoiding it is nice and all, but there really isn’t much you can do if a group of assholes wants to mess with you. Crossing the street isn’t going to help. Turning around and trying to get away before anything happens might work, but presumably you were going that way for a reason, and you can’t be so paranoid and scared that you turn around because someone a block away looks mean. Reality is, you’ll be too close to them in a subway or on a bus or train, and there isn’t much avoiding you can do.
Not much you can do when outnumbered. Even with training, if there are more than one attacker, the chances you would lose are huge. Best to try to just get through the situation without any violence occurring. I don’t mean to just hand over your money (unless they have a weapon), but do it if you think you really have to.
180lb is just a little above average. Without knowing what you are doing, killing someone is surprisingly hard. Humans are resilient. Look how much MMA fights result in death, and these guys are pros. Your size also doesn’t help you if there are 2 attackers or a weapon. Your attitude is probably the only thing that helps. If you look like a target, you’re more likely to be one.
For the OP, you sound like a good target. At the very least, your shoes made you a target. Once you knew some jackers might be watching you, you should have been more careful about where you go. Maybe this wasn’t possible though. No idea why you would get on the same bus as them. The end of your story where you get set up by your own sister really makes me wonder if these bad things happen to you for a good reason…
