Okay, so maybe I gave him a little too much credit. His hand opening and closing that I thought was a desperate plea for milk may have just been his hand opening and closing because he's figured out that it can. He does it a lot now and doesn't necessarily want anything to do with his cup of milk.
He does continue to communicate with me though mainly through whining and screaming and mainly to continously complain about the service.
It's a good thing he's so stinkin' cute when he's cheerful or else I'd be on the horn to the leader of that wolf pack I got him from to come pick him up and take him back to the woods. Let's see how he feels about the service around there.
