A friend once told me about a time they lost their wallet on a crowded subway. It was during rush hour, and they didn’t even notice until they reached their stop. Panicked, they retraced their steps but found nothing. Just as they were about to give up, a stranger tapped them on the shoulder. The person had found the wallet and followed them off the train to return it. My friend was so relieved and thanked the stranger profusely. The whole experience reminded them that there are still good people out there, even in the busiest cities.
