Eventually, Wimzie doesn't have enough money to buy what she wants from Mrs. Ferris' garage sale. She complains that "stupid" is just a word. But later, she learns a lesson about the power of words when Bo starts using "the word". She realizes that being called "stupid" doesn't feel good, even though Bo had no idea what it meant.
