DP went on his stag do last night. It was fairly quiet as these things go- dinner with a few friends then round various pubs and bars in our town. Only about eight of them, all in ltr or married. DP got in about 12, which was a lot earlier than I was expecting, and was also not nearly as pissed as I was expecting- he was actually quite upset, and said he'd left early as 'they were all trying to pull'. 
Now I'm not stupid- I know people can get a bit silly on a (rare) night out. A bit of flirting is one thing but one bloke apparently even took off his wedding ring! I know all these guys, and most of their wives/ gfs, and would have sworn blind they were not the sort of people to do this. DP seems really shocked - he reckons some kind of 'herd mentality' thing went on and they were all trying to one-up each other.
I don't know why I'm posting really- just can't believe this is apparently the norm?! And thinking my judgement (and DP's) must be pretty crap...
