Soon after my wife and I were married, we made a discovery. It seemed like when we argued, it was at night… when we were tired and irritable from a long day. So we set a curfew on serious discussions: nine o'clock is the limit. Now, when we start to get into a heavy talk after nine, we remind each other that it's late, we're not going to resolve anything tonight, and we can talk about it tomorrow. The next morning we're refreshed… we can talk about it calmly, or maybe decide it wasn't that important to begin with. For a humorous take on an argument curfew, take a look at a classic Monty Python sketch.
