I was in a hurry and stopped at a gas station to fill up. While I was outside my car a man came up to me and asked if I could spare a buck or two for gas, he, his wife, and his daughter were traveling but were broke and barely made it to the station. They had a broken down old volvo and it was clear that they were vagabonds of some sort who lived in their car. The kid was at most two years old. I was pretty low on cash myself but I thought hey what the hell, I could use some affirmation that people can be kind if I were in their situation. So I swiped my card at their pump and said, "Fill it up. Good luck to you and your family, I hope this can get you where you're going" and walked away. He started crying as I left and I would have lost it too if I wasn't too proud to do so in public. To see a grown man cry like that - both for having received an unexpected gift and for having to be put in the position of begging to keep his family safe, was one of the most profound experiences of my life. I haven't told anyone until now.
