I'm a very difficult person. My wife's a very difficult person. Living together is difficult but all marriages are the same - desperately difficult. ... I can't imagine letting a marriage go unless it's intolerable. Every time you get through a difficulty, the bond is stronger. If you're lucky enough to get to a stage where you have been together a long time, your lives are so intertwined. I think being polite and kind to each other is terribly important. That, more than anything, can go a huge way in relationships.
