A butterfly face

We were about to sleep and Ethan was lying beside me when he suddenly decided to move to Lani's side. 
Lani: Are you sleeping beside me or Daddy?

Ethan: You.

Lani: Why?

Ethan: Because I like your face. You have a nice face like a butterfly.
I'm not sure if that is funny or sweet. I guess it can be both. 

I can't see the butterfly, but I see a very beautiful lady.
