When I was a kid, my mom would get angry if we didn’t eat the crust from our bread. She used to tell us that kids in Africa were starving, and here we were throwing our crusts away. Not to be selfish, my brother and I gathered all the crusts we had not eaten, packed them in a box, and addressed it to Africa. The box came back a few weeks later, due to the wrong address. We felt terrible for all the starving kids we could have helped.
