When a man who had no friends was asked why this happened, he responded, "Friendship is like a diamond. It's rare, expensive, and there are a lot of fakes. If you made one mistake, then a second and a third, at some point you would say, 'There are no real diamonds in the world. There are only fakes." And another man added: "A friend is a person to be valued and treasured, but unfortunately there are rarely any friends in life you can really value."
