Each story begins with a choice, one made either by or for its main character. Consider Yaya. Yaya is a 40 something year old man who works in a garage; though he isn't supposed to accept tips personally, (there's a lucite communal tip box for the benefit of the entire staff,) from one customer to whom he's been exceptionally helpful, he accepts the neatly folded five that's pressed into his hand. Later that night, he'll use it to buy himself one extra drink, which will effectively keep him at the bar an extra 17 minutes; during that extra time, he will meet his next girlfriend, or get in a fight. On the other hand, he may use the extra cash in his pocket to buy himself two lotto tickets, a cup of coffee, and a bag of Doritos.
If he chooses to save the bill, and use it that night at the bar, and he meets his next girlfriend, perhaps she'll become his wife and give him two children, one of whom will attend Princeton one day and earn a doctorate in physics, specializing in magnetics, the other of whom will die of leukemia two days before her 11th birthday, or maybe the woman will give him herpes.
If he gets into a fight, maybe he will accidentally kill the man who started with him, or before the first punch, perhaps the two will reconcile and become fast friends, and discover they are from the same obscure part of Kenya.
Maybe one of the lotto tickets will win 2.00, or 34,000,000.00.
If it wins 2.00, maybe he will count himself lucky, bless God, and buy himself a muffin to eat later for desert, or maybe he will buy himself two scratch-offs, win nothing more, and curse himself for having wasted 2.00 when he could have had a muffin. Or maybe he will win a million dollars a year for life.
Maybe guilt, or honor will get the better of Yaya, and before moving onto his next customer, he'll quietly slip the bill into the lucite box himself.
Each story begins with a choice, and with each choice there are a million stories.
