Sometimes you find a $20 bill in the pocket of an old coat.
If you were broke or hungry, it feels like a miracle. It can feel like a miracle just simply by the mere serendipity of finding it when you didn't expect to. Maybe all this time you've missed it, or maybe all this time you didn't really know it was gone or what you'd lost.
It was always with you—until that moment you've found it again.
Whether you decide keep it forever as a memento or decide to spend it, you've already lost it.
