Living up to tough standards

After church, while waiting at the train station on the way to Pia's friend's birthday party. Dominic was playing with his new Rubik's cube:

Mommy: Dominic, did you show that lady in church how you were solving that cube?

Dominic: Yes.

Mommy: She was impressed. Her son was also playing, but it wasn't with something that needed thinking. But you, you were using your brain.

Pia: (always intent on being no worse than her brother) Mommy, am I?
