I know what it's like to have someone coming home who looks at you not in the way they used to in the old days, and I've seen my own face contorted with sadness and rage in the mirror.
My first husband, John Barry, was a composer. I couldn't believe that this sophisticated, talented genius chose me and not any of the other girls. I was so flattered, so excited, so in love with him. Of course, my parents were horrified, as he'd been married once and had a daughter with the au pair girl.
I had a baby at 19 and was a grandmother by 39. Now, my children lend me their children to take them off to Brittany. It's divine. I'm quite exceptionally lucky. I've never had a week without having all three of my daughters on the telephone.
I don't know why people keep banging on about the '60s. I came from a conventional family and I didn't go off with different people - I rather wish I had now, seeing all the fun everyone else was having.
When my father died, my mother came back from being Mrs. Birkin to being Judy Campbell. She was a stunning actress. She came out of her shell. She was herself again: this very independent, funny, intellectual lady - and was able to perform again, which was her life before meeting my father squashed it out.
Nothing has ever touched on what fun childhood was. Summer holidays were bliss. We made home movies, with real stories in them. My father had such charm and charisma, and made everything so funny.
Jacques Doillon wanted me to be in his film, 'La Fille Prodigue,' and there I was, expecting, for some reason, this great bearded man, when a splendid looking red-Indian style man appeared at my door. I said no to his film because I knew that if I said yes, I would run off with him.
One of the things I've discovered, thanks to the Japanese, is that you should enjoy yourself. In the old days, I used to think: 'Oh, never be satisfied, never admit to being happy.' But there's no curse in being happy.
My father was a painter, so I was encouraged to take a sketchbook everywhere. Cameras are perishable, but I still have tonnes of sketchbooks from all the trips I've ever been on. It gets you by when you don't know what to give people as a gift; drawings are good souvenirs.
