Latest issue of 'KindSpring Weekly' newsletter is themed Spotlight On Kindness: Unlikely Friendships. Herman Melville once said, "We cannot live only for ourselves. A thousand fibers connect us with our fellow men; and among those fibers, as sympathetic threads, our actions run as causes, and they come back to us as effects." This week's stories bring together some of the unlikeliest and sweetest threads. --Guri Mehta
