You see guys like us don't put up with shit like this and we arnt afraid if someone takes it too far we knock their f###ing head off. However as I said the bullies prey on the weak and people they know won't stick up for themselves. These people are afraid won't and can't stand up for themselves. Then they get hopeless and sometimes convinced that what the others are saying are true.
People talk how you need to take up for this guy or defend them. But when the big brother is away the bullies will play. The only solution is to teach the kids to stick up for themselves. Get them in the gym get them to gain some self-confidence.
