Once upon a time, there was an unseen giant. Nobody had ever seen him. He would play many pranks on the villagers such as lifting off the roofs of shabbily made houses and roll up the waves oh so high. Sometimes, he would even pull up great trees from the forest, and block the roads with them. But this giant also did some very good things. He would blow some air into a house when the mother of a very sick child prayed for some cool air, and he would carry tiny seeds on his back from the desert where they couldn’t grow all the way to the lush forest. This giant could whistle, and you have probably heard him a many winter’s night; sitting in front of a nice,warm fire. Can you guess what this giant’s name is?
