The Canterbury Tales: The Wife of Bath's Prologue Lines 354-362 Summary
You said that I was like a cat, because a cat would stay in the home of whoever damaged his fur.
If the cat's fur was shiny and nice, however, the cat would not stay at home for even half a day; instead, she would go show off her fur, and caterwaul (shriek like a cat) and play.
This is your way of saying that if I have nice clothes I will run around town to show them off.
