“Happy couples tease a lot when they’re in conflict and they tease in these really goofy, lighthearted ways that say, “The fact that you don’t do the dishes bothers me, but I still love you. It’s not that big a deal; we can work this out.” They tease in ways that allow them to express issues of conflict, but in a cooperative and pleasant way. It predicted how long they’d stay together.”
