After Marriage, How Do You Learn to Live Together?

When you're single and living alone, you don't have to think about other people's time or space.  Once you marry , and are sharing a home, you have to think about when the other person needs to use the bathroom, whether they pick up their dirty clothes, and where did they put that TV remote? Conflicting daily routines can cause the biggest arguments.
