Warm Fuzzy

Story 1:
Late one night Andrea woke up, needing to go to the bathroom. Being such a sound sleeper, it was not unusual that she was more sleep-walking than walking as she felt her way to the toilet. Tonight's walk seemed a bit shorter, and maybe it was for that reason that she stayed more asleep than awake. As she bumped into her seat, she automatically turned around, sat down and 'went,' completely forgetting to pull down her clothes first. In fact, she was in such a deep sleep that it wasn't until I came in the room and found her standing next to her bed and started cleaning her up that she even awoke.

Story 2:
Mark had gotten home late that night. It was already very dark and he was very tired. But being the devoted father that he is, when it was time, he helped put the girls to bed. And, of course, the girls begged him to stay and tell a story. So he laid down on the floor inbetween their beds and told them a story - putting everyone to sleep.
Hours later Mark was startled awake, a little unsure of where he was or why he was getting wet.

Story 3:
I was in the office trying to soothe and rock Hyrum to sleep. It was late and everyone else had been asleep for hours. Hyrum had just calmed down when Mark burst into the room and shouted, "She peed on me!" I looked up to see that sure enough, he was drenched and looking a wee bit yellow.

Conclusion:
Turns out Andrea never made it to the bathroom. In her sleep, Andrea mistook the first thing she bumped into (Mark sleeping on the floor) to be the toilet, at which point she proceeded to sit down and pee on him.
