In the early 1990s, I went to Philadelphia on a Mormon mission and lived in a tough section of the city. One day I received a letter from a friend. In it was $100 and instructions to spend it doing something nice for someone else. No spending the money on myself.
It was the holiday season, and I figured it would be fun to provide a great dinner for a family we had recently met who was clearly going to go without. We bought a turkey, stuffing, all the fixings, a pie and small gifts. I still remember leaving the box of food on the doorstep, knocking a few times and running.
