Just wondering

I was lying in bed this morning after Army of Dad left for work and the house was quiet. The kids hadn't woken up yet. Everything is nice and quiet. Then I hear my next door neighbor cough. Then, I heard him fart. Yeah, clearly our outer walls are not well insulated.

I know they have to hear us holler and yell during our semi-annual big argument. But, it made me wonder if , upon those rare occasions when the children are at my parents, and we're conducting some experiment involving monkey loving ... can they hear me from their front porch? Is that why he is always waving and smiling so big when he sees me?

*shuddering*
