A wish is a hope or desire for something. Fictionally, wishes can be used as plot devices. In folklore, opportunities for "making a wish" or for wishes to "come true" or "be granted" are themes that are sometimes used.
Some cultures have customs in which people are encouraged to "make a wish", such as blowing out the candles on a birthday cake, seeing a shooting star at night, tossing a coin into a wishing well or fountain or breaking the wishbone of a cooked turkey. Many believe such wishes can only come true if they are kept a secret from other people. Others, on the other hand, believe that wishes come true only if they are told to someone else. Others view wish fulfillment as a bad faith self-delusion. .
