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