Doctors don't need it

After dinner, Pia runs to the living room to play with her doll.

Mommy: (calling out from the kitchen) Pia, brush your teeth.

No response.

Mommy: Pia, brush your teeth

Pia: (playing doctor with her doll) MAAAHMEE...I'm a doctor!

Daddy: (??) Pia, go brush your teeth

Pia: Doctors don't brush their teeth.

Daddy: Yes they do.

Pia: But they don't brush their teeth while there are sick people in the hospital.
