A scene from “Unfinished Business”

Queen Elizabeth II: If I tell you something, do you promise it will stay between us?

Lord Porchester: Of course.

Queen Elizabeth II: This is how I'd like to spend all my time. Owning horses, breeding horses, racing horses. It's what makes me truly happy. And I actually think it's what I was born to do. Until the other thing came along that someone else was born to do, that they elected not to do. Which meant that first my father, and then I, had to do a job we were never meant to do.

Lord Porchester: Well, you've managed to make it look like the other thing is the only thing you were ever meant to do.

Queen Elizabeth II: You're kind. But it isn't. And on days like today, in places like this, in company like this, you get a glimpse of what it all might have been like. The unlived life and how much happier it might have made me.
