The terrible 2's and trying 3's are nothing compared to my 14yo DS behaviour!

He's so big and doesn't know his strength, I liken him to the incredible hulk! He is so incredibly argumentative, if I say the sky is blue, he'll argue that it is in fact orange! He has developed a strong dislike for his 2 sisters (12 and 8) and can't even look at them without lashing out, either verbally or violently.

This morning, for example, he threw his bus pass at DD12, which got lost behind the couch so he lashed out abusing her, hitting her and telling her it was all her fault! The family room then got trashed as he was trying to find his bus pass. I pointed out that he was making a mess, only to be given a mouthful about how I don't care and that it was his sister's fault his bus pass was missing! I tried calming him down, to no avail so I sent him to school without his bus pass. He mumbled and grumbled as he stomped out of the house, slamming the door behind him! I know that when he comes home this afternoon it will start all over again. After he's eaten every single item of food i the house that is!

This kind of thing is starting to become a daily occurence.

Please tell me this is a phase and he'll grow into a lovely youn man....PLEASE! Right now I can't see it.
