What men have called friendship is only a social arrangement... - Francois de La Rochefoucauld

"However rare true love may be, it is less so than true friendship."

"When we are in love we often doubt that which we most believe."

"We promise according to our hopes and perform according to our fears."

"There is only one kind of love, but there are a thousand imitations."

"If we are to judge of love by its consequences, it more nearly resembles hatred than friendship."
