Bizarro land

So I'm sat at F5 on my course and the instructor and the guy next to me are discussing what kinky underwear the wife of the guy next to me should buy. She is chatting to them on msn and sending them pictures of the underwear and asking their opinion. Whether or not she knows that the guy next to me is discussing it with the instructor or whether she believes that their conversation is private is another question.
Now don't get me wrong, if this guy's wife is into kinky underwear (and leatherware by the looks of the picture he just brought up) then good for her. Good for him as well. In fact I'm thinking that my wife should get some too. However, is there not a time and a place for this kind of thing? I understand that training courses are becoming less strict and are introducing a more relaxed atmosphere but when you can discuss your wife's underwear with the instructor whilst viewing the pictures on the training company's pcs have you not crossed a line?
Also, this training course isn't exactly intensive. This two day course could probably be done in one day but I guess the guys at F5 have to spread it across two days to justify the cost which means that I'm sat here twiddling my thumbs and writing my blog.
As I engage my ears again I can hear the instructor and the guy next to me discussing what chicks you can pick up when you are in the army/navy....
