For what its worth and being a father of 4 i have to agree in principle to what goatman has said.
I really dont know what posses's dads and/or relative to herrang kids in public and on places such as internet forums.
Cross with your sons atitude tuesday is ok acceptable.
Your a dad and likely to be his only backer.
At 12 the lad isnt liely to know what he wants from life - i know 40 year olds who dont know even now.
In closing sorry C's dad - bad move.
