That's an understatement!
When she giggled when the men chased the rat? There's nothing giggly and cute.
The pest control guy looked so shocked and annoyed. He was like "this isn't cute and funny. These aren't mice like at Disney Land. These are RATS and they can hurt you. They don't have bladders so when they urinate they urinate anywhere. On your clothes, in your food, and it will seem invisible because you can't see it."
I didn't know rats don't have bladders.
ETA: I chuckled when she said "you don't get a book for its cover" a la "don't judge a book by its cover"
If you cared about those books and other materials you wouldn't let rats take over these items.
