I tend to believe, when you're in a relationship, if you don't fight, it's not a real relationship. You have to have arguments and tensions, otherwise I don't believe it.
It's a marvellous life, a gregarious life that we've had. We're very lucky in that way. Unlike writers or painters, we don't sit down in front of a blank canvas and say, 'How do I start? Where do I start?'
