M's Yarn

M stayed at our house one weekend when he was about 3. He had a small piece of yarn that he carried with him the whole time. Sadly, though, he forgot the yarn at our house.
About a week later, M got an envelope in the mail.
M: I think Erma and Scout sent me my yine!
Busymommy: They did not send you your yarn. Why would they do that?
And sure enough, Erma and Scout had sent M his yarn. (shows what parents know)
