What changed me was discovering that even in a season when I felt reduced to need, I still had the power to choose how I treated someone else.

Walter did not turn that moment into a promise of a future fortune.

He went home, called his grandson, rebuilt relationships, and spent many years helping people without insisting that they thank him.

When the time came, he supported a community organization because its work mattered to him.

That decision was his, freely made.

I think about the bill occasionally.

It was folded and damp, softened by too many trips between my fingers and my pocket.
