Daddy is a princess

Neither of us were quite sure what to think of this...

One night, Eric came into the bathroom like this while Tessa was brushing her teeth. Tessa thought it was a hoot. (It was.) But when he left...

Me: "OK, my strawberry princess, let's finish getting ready for bed."
Tessa: (In a sad tone) "I'm not a princess, Mommy (she put her head down in her hands). Daddy is the princess. He has my tutu!"
