My teenage son is becoming revolting in nature.?

well i am also an indian but now settled in us,im familiar about indian conservative society and its culture.i think he has some sadness in his life which is hidden in his inner mind try and talk with him to find it out.if it gets ok then its fine otherwise i advise you to send him to some hostel come schooling i know it will be hard fr u bt it may benefit him to find himself with other kids of his age..
