Dao is too tired to try to figure that out. He flops into the guest bed.

He's not sure how long he sleeps for, but the room is a lot brighter when he gets up. He sits on the edge of the bed for a bit, and then feels a vague obligation to straighten things up in memory of how immaculately tidy the room was when he got here, so he does that, and then he sits on the edge of the bed again and feels very awkward.
