Vanya's phone conversation

Vanya is really obsessed with the phone. I mean really obsessed. Whenever we get a phone call, he screams until we give the phone to him. Then he simply smiles and says either "Uh huh" or "No" (especially when we ask him to give the phone back to us).

For some reason, he has more conversations when there is no one on the other side. But tonight, I heard him carry on a real conversation by himself:

(Ring)
(picking up)
"Hi, Abe (his godfather)."
"I'm coming."
"Bye."
