Smowball, that sounds just like a well behaved version of me when I was that age., I grew out of it as I developed a conscience, I would love to be able to give you advice, my Mother was a great believer in patience and understanding, it certainly worked on me. Have you tried a real Mum to Son talk? thats what worked on me, it always left me feeling guilty of what I had put my Mum through and being able to understand consequences.
It may be a hard slog but work at it.
Good luck
