I Sleep Here

The last few nights Bob has been restless in the hour or two before bed. He will get up from his chair and walk across the living room to the hallway- look in all directions- then turn around and announce to me as he is pointing at his bedroom, "I sleep here"
I will say " You sure do". He will do this over and over and over, about every 5 minutes.   On one hand-Its driving me bonkers-On the other- He is definitely getting some exercise in so I'll keep my lip zipped!
