"I have to go," he replied and left our room.
Ok, he needed to use the bathroom. No big deal. Then a few minutes later I heard giggling coming from the kitchen. A silence followed, then more giggling. Let me just say this child giggling in a dark house while we were all in bed sounded more like something from a creepy horror movie than I'd like to admit. Mr. Dog decided to go investigate.
"What are you doing?" he asked.
"Hey, Big Dog. What are you doing?" he asked again
"Do you need something? Are you ok?"
Again with the creepy giggling.
Finally the kicker. "Wait. What are you doing with your pants down?" a pause. They now had my full attention. "I sure hope you didn't...." and he trailed off. "Oh crap."
"Come on, Let's get you back to bed," said Mr. Dog, and two sets of feet padded off to put Big Dog back to bed.
While I was curious, I was also cold. And sleepy. And not about to get out of bed, so I hung tight. A minute later the kitchen light flipped on and Mr. Dog set about making a ton of noise, chuckling to himself occasionally.
When he came back to bed, I asked what happened. Turns out we have a little sleepwalker. In his zombie-like state he mistook the step stool in the kitchen for the toilet and, well, doused it.
I'm just glad Mr. Dog thought it was funny. As he gave me the rundown, he also told me he has a vivid childhood memory of waking up to find himself peeing in the kitchen trash can. I guess the apple doesn't pee too far from the tree after all.
