I enjoy the company of my close girlfriends, particularly going for a meal/coffee and a chat, more on a one to one basis than a crowd these days. although in my younger days we would have regular weekly meet ups with say about 4 to 6 of us, but it was really for a good old chat and catch up usually in a wine bar and we were never out on "the pull".
Similarly whilst my husband like the camaraderie he gets from the company of male friends, he prefers the company of women and does not like going to say an all male dinner. Neither of us would ever want to go on a hen or stag do. We have a timeshare in Bournemouth and avoid the town like the plague on week-end nights, when marauding hen and stag parties are on the prowl they make the whole place seem really feral. A friend of mine had to fly back to the UK from Malaga recently and said the airport lounge was chock a block with these parties, all British of course, and it seemed to her that they drag all members of the family along, including grandparents. She told her partner she would never fly in or out of there again cos the behaviour of the stags and hens was so awful. I think it's sad some young people feel they have to have these dos as it might give them the opportunity to have one last fling, if that's the case, perhaps they should not bother getting married.
Possibly it's generational, I think hen and stag dos, if indeed we had them at all, would have been on a smaller scale.
