that is a very unfortunate line and i hope he grows out of that kind of attitude has he gets older. he's still pretty young. not that that's an excuse, but he's not exactly all grown up.
I have a feeling it will only get worse. He seems to have a big sense of entitlement, and I don't see that attitude going away any time soon. Maybe waaaay down the road, if ever. He's old enough to know better. He's just dumb and ignorant.
