One beautiful morning the witch crept up to Tim while Maggi was playing with their daughter and whispered in his ear, "See here, Tim, look at all the Fuzzies that Maggi is giving to Lucy. You know, if she keeps it up, eventually she is going to run out and then there won't be any left for you."
Tim was astonished. He turned to the witch and said, "Do you mean to tell me that there isn't a Warm Fuzzy in our bag every time we reach into it?" and the witch said, "No, absolutely not, and once you run out, that's it. You don't have any more." With this, the witch flew away, laughing and cackling.
Tim took this to heart and began to notice every time Maggi gave up a Warm Fuzzy to somebody else. Eventually he got very worried and upset because he liked Maggi's Warm Fuzzies very much and did not want to give them up. He certainly did not think it was right for Maggi to be spending all her Warm Fuzzies on the children and on other people.
He began to complain every time he saw Maggi giving a Warm Fuzzy to somebody else, and because Maggi liked him very much, she stopped giving Warm Fuzzies to other people as often and reserved them for him.
The children watched this and soon began to get the idea that it was wrong to give up Warm Fuzzies any time you were asked or felt like it.
