yeah so the solution is to stand there and get punched
great solution lol
If you fight back, you'll still get punched, plus you'll get suspended. I'd much rather just get punched once or twice before it's broken up.
However, I don't put myself in those situations to begin with. I knew most the people at my school, all of which liked me (at least as a schoolmate if not as a friend). The people I didn't know didn't seem to have an issue with me.
If you're having to worry about getting into fights, then maybe you should just be more friendly to people. It never hurts to be on good standings with people.
