Frugal...
Mary's fourth grade homework assignment was to make sentences using the words in her spelling list, along with the definition. Coming across the word "frugal" in the list, she asked her father what it meant.
He explained that being frugal meant you saved something.
Her paper read: "Frugal: to save."
Sentence: "Maid Marion fell into a pit when she went walking in the woods so she yelled for someone to come get her out. She yelled 'Frugal me, Frugal me!'"
