bullying is a tough subject, if parents jump in too far, too soon they take all sense of self confidence from their kids which makes bullying worse.
Bullys pick on people that seem like they can be bullied, people who the bullies think will take it, kids that go crying to mummy reinforce the idea in the bullies head, AND the kids head, which makes them a target in the future for other bullies even if on the slim chance that one bully is taken care of.
Running is generally a bad idea aswell as again it reinforces the idea you're a target, you're weak and susceptible to bullying. Teaching your kids to run away, or tell you straight away, its a hard thing, severe bullying isn't bullying, its just thugs who could do serious damage. But the guys who trip you up in the hall or throw your books around or something won't get in trouble for minor stuff, and will continue doing it, getting help will make it worse.
Friends can help, but again if you tell a friend, hang around them all the time bully's will just wait for the moment you aren't with them, or if your friend has to step in every time again it teaches the kid they are a bullying target and will always be weak in the situation.
Theres no right or wrong, its a fine line, one kid at school wasn't a bully so much and we were on friendly terms being in the same tutor group when we started at high school. But later on he turned into a pratt and hit a friend of mine, I got in his face and he decided he'd have a go at me constantly. It ended up with him sweeping my stuff off the table sitting down and saying it was his seat now, after months of crap I kicked him out the chair, he stood up punched me, and I just took it, he realised I wasn't scared of him, didn't need to throw punches, wasn't going to take crap and I don't think he spoke to me or did anything to irk me for the remaining time at school.
This other pratt that went around punching people decided to have a go at me one day, I shoved him over after he did something, though can't remember what, he got up, punched me, it hurt but I didn't react, I didn't try and beat him up, I doubt I could have, however he was waiting for me to try and kick/hit him so he could beat me up, it just never happened, never had any more grief with him either.
I wasn't a big kid in school and he was the tallest/well built guy in the school, its not about size, its not about personality(usually) its just about the way your carry yourself, if you act the victim, you'll be victimised, if you act somewhat confident and that you won't just take whatever they have to dish out, and more importantly, really don't care or think about them at all, they don't have a weak target who won't fight back, thats what bullys are looking for.
As for Asim, doesn't he just constantly spout utter tripe, another case where I just don't believe him at all, sounds like the kind of ridiculously crap dialogue you find in the bill. If it happened as you said, well, way to act like a victim. You may have thought you bought yourself some good will from them, but you were just getting in deeper and deeper, what would have happened when they had something serious on them, had some weed in school and decided to hand it to you just as they were about to be searched, you got in trouble and they all said it was yours. They weren't your friends, but were using you and they'd have hung you out to dry whenever it suited them.
