Qatar is a vibrant, young, multi-cultural society for both expats and nationals. There are laws which govern personal behavior but there are some excesses, of course. If you are expecting a strict adherence to or enforcement of social mores you might well be disappointed here. That said, most of us on QL would never have an affair or would engage in any illegal behavior. Personally I would be offended if someone even suggested that by contributing to this website I would be condoning such behavior. Most of us just have a good time working out how to "live and let live" in the give-and-take of a pluralistic environment and all that entails.
