Not so much in my area. It always came as such a shock to me when a couple seperated or divorced... almost without fail they had put on a great act, giving the impression of the blissful happy union, when in reality it was anything but behind closed doors.
Either that, or there were a lot of couples who were extremely detached from eachother. They spent their time before and after the meeting on opposite sides of the building and didn't seem to really acknowledge the other too much.
