Rationale of a 3-year-old...

I just gave the girls an early bath so we can eat dinner and head to church tonight.  After I finish bathing/dressing them, Sarabeth says she has to wash her hands.

me: Why? You just took a bath so your hands are already clean.

Sarabeth: Kuh-buz (because) I was very tired when I got up this morning.

me:  So that means you need to wash your hands?

Sarabeth: Well, Sure!

She was certain her answer was justified, and she now has clean hands and a soaking wet shirt.  Nice.
