Mostly, whenever children reach to a age of 16(teenage) parents stop supporting them mentally. Not everybody but mostly they do...In someway they start to take care of only his material needs..

But being through that phase as a child myself.. I can say, it's like a bridge phase. Many things that you thought as a child start to turn false, the world is shown to you in a different way, people start treating you in a different way all of a sudden. And this is not enough, with all that...
