The following is the entirety of the phone conversation I had with Luke this last Sunday morning (I was in Chicago; Luke was in the kitchen):

Daddy: Hi, Luke!
Luke: Hi.
Daddy: How are you doing? Did you sleep well?
Luke: Slee.
Daddy: Are you having fun with Mommy?
Luke: Momma.
Daddy: You be sure to be a good boy.
Luke: Gooboy.
Daddy: Are you going to play with your toys today?
Luke: Toe.
Daddy: Are you going to play with Zoe?
Luke: Zozo.
Daddy: Okay then. I love you!
Luke: Olio.
