Luke and Hannah's Thoughts on Annunciation

We had an interesting conversation with Luke about Annunciation this morning. It went something like this.
Mama: Were going to church for the Annunciation. Its a special feast in the church when the angel Gabriel appeared to Mary.
Luke: Why?
Hannah: Why?
Mama: The angel told Mary she was going to have a baby.
Luke: What baby?
Mama: Baby Jesus. The angel told Mary she was going to have baby Jesus.
Luke: Yaya's Mary?
Mama: No, no not aunt Mary. Mary the mother of God. The Theotokos.
Luke: OH!!
Hannah: OH!!

I wonder what was going through their little heads at the thought of there aunt Mary seeing an Angel and having a baby!
