It talks about boys feeling like they cannot ask for help when they are being bullied or even offer it. The pent-up emotions create frustrations and depression. Boys are sometimes unable to identify bullying as a problem and harmful while girls notice bullying and stand against the bully. Girls can identify bullying as inappropriate which helps them stop unacceptable behavior.
