My youngest is 14, nearly 15.
His DF and I split up earlier this year and he has a lot of anger, but how much of that is down to his age Im not sure. He's a big lad, 6ft and a rugby player. He has 2 older brothers but they are in their 20's and the world is a different place since they were teenagers!
I have been a little too easy on him for a while to 'compensate' for the split, but I think I have to start to toughen up a bit!
What do you expect from your teen? or is it just all a matter of negotiation?
