My carpet doesn't match the drapes...

So today my brother-in-law and my nephew came over to help put the new carpet down in my living room. Everything was going fine until my nephew started to have a temper tantrum...AT 14 YEARS OLD! It started with him and my bro in law arguing about something about school, and escalated from there. It almost seemed like the kid was goating him. Just arguing for the sake of arguing. Eventually he started full on yelling at the kid...which i don't blame him one bit for...he was backtalking like no tomorrow. During this whole thing me and my father were right there...and even HE had to walk away. Later on in the day he said to me, 'I am so glad you and Wayne (my brother) were never like that...that kid needs some psychological help.' And i agree with him. I understand that kids will be kids, but you have to respect your parents....at least till you're 18 and mature enough to decide whether they DESERVE your respect or not. I mean i was NEVER a saint in my childhood, but i kept the disrespect and backtalking to my parents to a minium, and never at that level. I'm worried about that kids future, cause if he acts like this at 14, how is he gonna act when hes 19,20,21? You can't hold a job with an attitude like that, or even get through school like that. Maybe it's just me getting older but it seems like im having a harder time relating with the new generation. Plus their music sucks ass.
