The client's wife states that she wants an addition to the existing stable that will be merely a new, second building matching the present. Architect Cooper tells her that he had acted upon his understanding that an entirely new stable be built using part of what's there. She tells him to do it her way. Because I can't do anything that I don't like. Yes, indeed he is, and he's decided to do them my way.
Cooper says nothing.
She cheerfully nods approval. You've been very patient with me, and my stupidity. I notice that they were finally built your way. Oh yes, yes, I can see now that I was quite wrong about them. The inability of two fans of the film to remember its detail is something of a testament to its quality.
