Maybe sharing a room is okay

Pierce sure loves brother Graham. When asked by me if he wanted to sleep in my room tonight (Mitch is in Madison with friends for the Wisconsin vs. Ohio State football game tomorrow and Max and Graham are Scouts night at the hockey game then staying at Ian's), he says

"just until G gets home. Then I want to go to my room."

Me, "Graham is sleeping at Ian's house all night."

Pierce, "but I always want to sleep in our room with him."

Makes me smile but I do wonder, how long will this last?
