...what was the friend thinking would happen if she and the wife treated him like that? Him saying "Excuse me, ladies, but I prefer to have you stop it now and let me go to the bathroom to finish this off by myself!" or the like? Let me tell you, dear female friend: What you experienced here is a typical male reaction...you might come across this more often if you keep up your research work.
In other words: Thanks for sharing!
