A Sleepy Conversation

I overheard this on the monitor today, minutes after bedtime:

Ace: Benny?
Silence
Ace: Benny?
Silence
Ace: Benny?
Silence
Ace: What are you doing over there, Benny?
Ben: Ben is trying to sleep, Ace.
Ace: Benny?
Ben: Close eyes, Ace.
Ace: Ok, Ace closes eyes and mouth.
Ben: Ben closes eyes and mouth too.
Ace: I'm doing it, Benny.
Silence
Ace: Benny?
and so on...
