lol, he wasn't trying to diss youngins like yourself, just trying to diss that particular person. believe me, being 11 isn't a bad thing, and being 12 isn't a bad thing either. you shouldn't take too much offense to this, cuz in a few years, you might say "man, you're acting like your 8 years old, what's the matter with you" and then you'll understand. the person just wasn't acting their age. he didn't try targeting your specific age, just trying to say "grow up and act your age"
