That's good advice, Iluv. You should definitely take it to heart, Vin.
Try and avoid having friends in your life that are confrontational. Those kind of people will get you into bad situations. If you think your friends are like that then you should stop hanging out with them. You don't have to feel the need to jump into every fight one of your friends gets into. It's their business. they shouldn't be forcing you into their problems anyway. There are situations where you should get involved, like if their getting beaten up by a bully, or picked on in anyway, you should help. Not necessarily by getting physically involved; Unless you find it absolutely necessary.
