[EX Q]: Article: I have forgotten the name of an old lady who was a customer on my paper route when I was a twelve-year-old boy back in 1954. Yet it seems like just yesterday that she taught me a lesson in forgiveness that I can only hope to pass on to someone else someday. On a Saturday afternoon, a friend and I were throwing rocks onto the roof of the old lady's house. I found a smooth rock and sent it.
