The problem is that he's too hot in the house. He likes to be in the garage, where it's cooler, but he doesn't want to be out there alone. So I'll go out, do some of my woodworking and stuff, but as soon as I go inside he starts barking. He won't come in.
Then, when he does come in, he goes to the basement because it's cooler down there. Then he realizes that I'm upstairs, wants to be with me, but can't get back up the stairs.
When R gets home he sits in the garage, watches TV, has a few smokes, so Indy is happy. So you, I guess he does miss R, in a way. ;)
