its not your or LEGO's fault, or his brothers fault. its the bully fault, they're just people who beat people up for the fun of it.
his brother stood up for BIONICLE and thats good, if he was strong a bit (40-50%) he shouldn't let the bully beat him up. bullys are a bunch of stuck-up #####'s and are afraid of everyone, thats why they beat up on people.he should have at least punch the bully in a pressure point to show he isnt weak. and if he obsessed over it, his brother should have talked about it
and at least ask him to join something or get another hobby and not dump BIONICLE, and this happened to me with a lot lot of stuff, music i like BIONICLE etc. etc., and if someone with authority was there, the brother who was getting harassed should have told the person with authority, and if they call him something bad just forget about it! it doesn't matter if they call him something, at least he'll be off without getting bruised and beaten.
