In fiction a wish is a supernatural demand placed on the recipient's unlimited request. When it is the center of a tale, the wish is usually a template for a morality tale, "be careful what you wish for"; it can also be a small part of a tale, in which case it is often used as a plot device. One can wish on many things for example: wishing wells, dandelions when one blows the seeds or light them on fire, stars and much more. When one wishes on a well, a coin is thrown in and the thrower silently makes a wish in the hope it comes true.
