Hello?

It was the cutest thing!  This morning I came downstairs to get Kai out breakfast and, well, just because we hang out in the mornings together while I check email.  I always call through the door before I open it so I won't startle him, then give him a second to wake up.

Me: Good morning, Kai!  Good morning!
Kai: Hello!
Me: Awww!  You're such a good boy! Hello!  Hello, Kai!
Kai: *whistles!*

It was the cutest thing, I swear!  I've taken to saying "Hello!/Good Morning!/I'm back!" when I come in/return to him, and "Be Right Back, BRB!" or "Good Night/ Nighnight!" when I leave for the night.  I think he is beginning to understand the meaning of my various greetings!  He's such a smart boy!
