My son in his Army uniform for the first time

My 16 yr. old son picked up his army uniform and gear yesterday. I don't know about you but I think this a great pic and he looks so handsome. He is very much against us taking his picture but I snuck up on him for this one. Unfortunately, he is really angry about this. He has been very mean and rebellious to me and even to his girlfriend with whom he is in love very much, not just about the pic but about everything recently. I don't know what's going on in his head, but he is hurting all of us, his family and friends with his sarcasm and rebellion.
