What is he thinking?

We finally got our bedroom put back together yesterday afternoon. We decided to do some rearranging of the furniture (all 3 pieces... yes, it is sparsely furnished). We moved the bed to a different wall and the chest to the wall opposite where it used to be. The nightstand now sits adjacent to the bed, but is angled in a corner instead of being right next to the bed facing out. We now have a huge amount of free floor space at the foot of our bed. (Hey... there's enough space to put down one of the Oriental Rugs my husband bought in Oman a couple of years ago... the rugs that are rolled up in our closet and have never been spread out on a floor other than to examine them when he brought them home. Will have to think on this...) Anyhow... the dog is totally freaked by this. He walks into the room and sits in corner and looks like he has lost his best friend. I wonder how long it will take him to realize it's the same room and he is still allowed in there?
