I said, "sing it!"

Lena:

Daddy, sing Puff the Magic Dragon.

I continue putting on her pants and don’t begin singing.

Lena:

Puff the Magic Dragon, lives by the sea.  And frolics in the autumn mist . . .

Daddy, do you know what “autumn mist” means?

Me:

Do you know what it is or do you want me to tell you?

Lena:

It means the words of the song and you have to sing it!
