Madame de Rosemonde: I'm sorry to say this, but, those who are most worthy of love are never made happy by it.

Madame Marie de Tourvel: But, why? Why should that be?

Madame de Rosemonde: Do you still think men love the way we do? No... men enjoy the happiness they feel. We can only enjoy the happiness we give. They are not capable of devoting themselves exclusively to one person. So to hope to be made happy by love is a certain cause of grief.
