I thought when he was stating that he was older then Masta he was specifcly trying to stop him from calling him
"kid" any longer. Think of your teacher, for example. If you where to teach him/her for a day, your most likely not going to say "kid" Due to respect, and the obvious age. Do not dwell on stated ages either.
5th graders mainly like to act cool and all grown up. So they'll get around, say one word, like
research, Or, CRAP! And laugh their ASS'S off. Anyway, Im ranting off topic. Sorry, What im saying is, Ages are fake on the internet. Every single one, And you should never say "Im older then you" Cause it makes you sound like a stalker. Good day.
