metaphor

Love is a sweet melody that haunts those that like your singing. Let it go, and it will come again in another form. If you don't let it go, it can never return, for a vessel that is full cannot be filled. But a vessel that is empty can be filled with rich new wine that you never tasted before. And the new wine doesn't destroy the memory of the old, but enriches your palate and your sense of having lived much. Unused palates don't know good wine from bad.
