Are you?

Scene: Daughters are in their beds, waiting for me to come in and check on them. Their room is dark in a somewhat futile attempt to get them to stop playing with each other and go to bed. They've finally settled down and so I come in very quietly.

Younger daughter (realizes I'm there, but can't see me): Is you my mommy?
Me: No, I'm your daddy.
Younger daughter: Is you my daddy Bise Aldn Say?
Me: Yes! (big happy smile) Yes I am.
