Words are so easily spoken that we forget what power they have to give pleasure or pain. They seem to vanish so utterly the moment they have dropped from our lips that we forget they do not go away at all, but linger, either like barbed arrows in the heart where they struck or like fragrant flowers distilling perfumes. No matter when we talk with others or on what theme, however playful or light, we should always try to speak some thoughtful word before we part, some word that will give strength or hope or cheer or help. We may not meet our friend again.
