he has no sense of responsibility nor the maturity to handle himself.
people say that he is intellectually mature <-- sorry. he is immature even though he has the brains.
you got to give it to him because he got the guts to say his mind
but he has no EQ, not the brains to know tat this is not d time to say stuff like that.
there are many kids out there as smart as he is, but they are more responsible and sensible, unlike him. you may say that they have no guts, but i would say that they know what is the right thing to do.
