hate to break it to you but
He's saying that you're a kid BattleBeard (which you totally are. Didn't you just turn 13?) So it's weird for you to say you hate kids.
Anyway, I love kids. I work at a used children's clothing store. I've always loved kids. Maybe it's because I'm pretty much a kid myself (at least mentally. I guess I'm physically a kid to some older people too), so I get along with them well. I can occupy myself with our toy shelf for hours. There's something magical about the honesty and purity of kids. I kind of hate kids who swear and try to act older than they are, though. An eight year old (or even a 12 year old or 13 year old) shouldn't be saying 'shit.'
