In my city there are quite a few homeless people. Once, coming back from a dinner in the downtown area, I saw a homeless man animatedly telling an older teenage boy about a book he had just finished reading, and then as the boy asked for the name so that he could read it too, the homeless man gave the boy the book and told him that he could just bring it back next time he ran into him. I still think about the generosity of this man who had nearly nothing.
