K when I first read this, I thought the quote was "I'm all right" meaning I'm always right. But nope, i'm just a dum dum. 

For those who didn't get it, his mom told him 'you're allright' like you're ok. Then his parents divorced, but he brushed it off becuase he's "allright." Then bullies, death threats, etc. all came to him, but he was 'allright.' then this kid who gave him a quote from a book told him that he wasn't and that it's ok to express feelings.
