You would be the "new kid", yes. Hell, I still feel like I'm new around here, so what does that make you?
And also the "dumb" part, I'm fairly certain that's you as well.
"What does that make me"? Not a kid for certain. Especially when it's a kid who just reached puberty, that is calling me it.
I'm inclined to disagree with the rest.
I have newbie attitudes sometimes sure, who hasn't. Even genius make stupidities sometimes, that makes them dumb? By your own terms, I guess yes.
