ZY does this a lot:
So we had this exchange more than once:
mf: Look at him! His mouth is smaller than his nose - so cuuuute! *swooning*
Sito: He's like Hello Kitty!
mf: Eh, Hello Kitty has no mouth *.*
Then one day, Sito had a follow-up question: Is he the height of three apples?
PS: As I wrote this, I discovered that she measures five apples tall and weighs three apples. We've always thought she measures three apples tall!
