Three Going on Thirteen

As we are driving to school this morning, I comment on the cloudy skies, and further:

Mama: Do you think it’s going to rain today?
Viva: The sun is out. Don’t mention it.
Mama: Don’t mention it?
Viva: You can see the sun, so don’t even mention it.

We stop at a traffic light. I grab a Washington Mutual deposit envelope and start scribbling down our conversation.

Viva: What are you writing?
Mama: I’m writing down “don’t mention it.”
Viva: Why are you writing down “don’t mention it”?
Mama: I thought it was a funny thing to say.
Viva [in a tone that implies this is blatantly obvious]: Well, it is a funny thing to say.
