Dad can do it better!

Picture Libby and Mia at the kitchen table. Libby is watching Mia put together a box for her class Valentine's Day party. (Whatever happened to the days where we made Valentine boxes at school?) I am at the kitchen sink washing dishes, and I hear this:

Libby: Why aren't you waiting until Dad gets home?

Mia: Because why wait, when I can do it myself?

Libby: Dad can do it better!
