Quote context

[...]

- Sibyl has made me forget your poisonous theories.

- Which theories?

- Your theories about life, about pleasure.

- Pleasure is the only thing worth having a theory about. It's nature's sign of approval.

- When we're happy, we're always good. When we're good, we're not always happy.

- Sibyl is the answer to all your cynicism, Harry. I believe you'll understand that when you see her.

(All singing) So goodbye, little yellow bird, I'd rather brave the cold on a leafless tree than a prisoner be in a cage of gold.

- This marriage is quite right. I didn't think so at first but the moment we met her, I was convinced of it.

- She's charming and innocent, transparently so.

- I knew you would say that.

- She's all that you say, but I don't agree with Basil.

- I believe she loves you so much, you have no need to marry her.
