Raisin A dried-up grape is referred to as a raisin. It represents a long-sitting unrealized desire that loses its "juice" or spirit and then shrinks, much like a raisin. A postponed dream kills us, like a raisin in the sun. Because the discomfort is neglected, it will worsen and fester like a sore. At its worst, it can cause death. People say things about you from the moment you're born until you die. Not only what people say but how you react is all that matters. Nobody ever died of shame. So don't worry about what others think of you. They never did understand you, and they never will. "He's not worth salt." This means that you aren't valuable enough to be sprinkled with salt. Salt was used as a ceremonial purifier in ancient times. This metaphor tells us that someone who isn't considered important by others should not attempt to make themselves important through self-aggrandizement or dishonesty. "His heart is as hard as rock." This means that your friend doesn't have any feelings at all. He is cold and heartless. There is no trace of sympathy in him for anyone else. You would get along well with this person. This means that your friend is ruthless and does not care who he hurts in order to achieve his goals.
