That wasn't the only complaint :) It was more the overall uninterested feel and senseless macho behavior that maybe they have pent up being with the wife or something and they need to act the tool to justify their manhood. Or to forget the day to day family routine or something. Most of the time they sit around bored.
What my friends don't know is that I'm pretty 'liberal'. And I don't have this pent up need for horseplay. I get enough of the more real kind of play :) I just felt so out of sync. It's just so senseless and not enjoyable at all.
The kind of event is pretty common in Holland. It's a pretty typical thing for male friends to go off for a weekend once a year or so in a cabin somewhere. I've done it with several different groups.
