Such fun as games with matches carries great trouble. If in most cases these games end without consequences for the child and adults do not even know about them, then sometimes the result of these pranks becomes a more deplorable result. Preschoolers learn everything by looking at adults, and if in the hands of an adult matches are harmless, then in the hands of a child they can bring a lot of trouble.
