No matter what some people in America say you played "the game"
plain and simple. I for one will not vilify your decision to look
out for your own interests. You are entitled like everyone else to
pursue the American dream at whatever costs and would have been
foolish to waste the opportunity.

In real life, people "reconsider" their commitments all the time.
Yau-Man's decision to make the deal with you was a strategic one.
He took a calculated risk when he made that deal with you. He
figured out of all the other players you wanted, in fact needed that
truck more than anyone else because of your impoverished
background. Well he underestimated your ability to play the game at
his level. At the final tribal council based on the questions you
were asked (i.e. How many zero's in 1 million? What a loon!) I guess
the other players did the same.

In the end, if he had truly respected your game play he would have
at least attempted to try to convince you to stick to the deal and
therefore secure his place in the final 3. He was so confident that
you would give up 1 million dollars out of "gratitude" for a $60K
truck, how truly dumb you would have been then if you did?

You played a great game and put your strongest opponent in
checkmate. Even though you did not win the million dollars, you are
still a winner and your sons should be proud of their father.
Without really knowing you, it is my impression that you are a man
of honor who is committed to taking care of and providing for your
family "in REAL life". If possible, give serious consideration to
Yau-Man's advice and get the formal education you will need to shape
the future you dream of. Best Wishes and God Bless!
