Behind the bars

Heard terrible noise upstairs after Mrs.Mrok had bathed (?) the kids. The noise was actually screaming and laughter as S was running naked around the bedrooms and the upper hallway carrying some toys from one place to another.

I wonder where does that primitive joy come from when kids get away from their clothes? Or when some guys meet up and get drunk and the same happens in some respect?

Weird isn't it ;)
