A boy gives a cookie to a mouse. The mouse asks for a glass of milk. He then requests a straw (to drink the milk), a mirror (to avoid a milk mustache), nail scissors (to trim his hair in the mirror), and a broom (to sweep up his hair trimmings)
Considering that the whole point of the book (and its sequels) is that the story is a neverending loop, how can the mouse repeat his actions? Shouldn't he get stopped by the trimming his whiskers part? After all, once they're trimmed, they're trimmed?
