In 1869, William E. Story promised his nephew, William E. Story II (then sixteen years old), $5,000 (about $120,000 in todays money) if Willie would abstain from drinking alcohol, smoking, swearing, and playing cards or billiards for money until the nephew reached twenty-one years of age. All of these were legally permissible activities for the teenager at that time in New York State. Willie accepted his uncles promise and did refrain from the prohibited acts until he turned twenty-one. When the young man asked for the money, his uncle wrote to him that he would honor the promise but would rather wait until Willie was older before delivering the money, interest added on. Willie agreed. Subsequently, Willie assigned the right to receive the money to one Hamer (Willie wanted the money sooner), and Story I died without making any payment. The estate, administered by Franklin Sidway, refused to pay, asserting there was no binding contract due to lack of consideration: the boy suffered no detriment, and the uncle got no benefit. The trial court agreed with the estate, and the plaintiff appealed. Should the court on appeal affirm or reverse? Explain.
