What the???

I woke up at 3am to pee and saw this pile on the floor in the office area - At first I thought maybe Mark had put some dirty laundry there then I looked closer

I put him back in bed and he was soaked!  Our room is about 80 degrees and he had wrapped himself in a blanket!

In the morning I showed him the pic and told him "Look what I found in my room!"  He just smiled and said he "snuck in quietly"
