 SOUR GRAPES is what you get when lots of money ignites a runaway chain of events including deceit, destruction and dissolution all because two cousins can t figure out how to share 50 cents. Richie, a sneaker sole designer, and his cousin Evan, a brain surgeon, are spending this weekend with their girlfriends in Atlantic City. Having exhausted their gambling funds, Richie drops his last quarter into a slot machine. Evan advises him that he needs two more quarters to really make it big and proceeds to give him the extra coins. Richie pulls the lever. Moments later, three grapes across, Richie is scooping up a $436,000 jackpot. Does Evan get two-thirds of the payoff for two-thirds of the investment? Not in Richi s eyes. How about half? No dice.
