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

“True sorrow is as rare as true love.”

“True friendship implies full confidence, which may only be completely given or completely withdrawn. If friendship has continually to be analyzed, nursed, and cured, it will cause more anguish than love itself, without having love's strength and its remedies. And if this confidence is ill-placed? Well - I would rather be betrayed by a false friend than deceive a true one.”

“The process of falling in love at first sight is as final as it is swift in such a case, but the growth of true friendship may be a lifelong affair.”

“But sorry is the Kool-Aid of human emotions. […] True sorrow is as rare as true love.”

“There is nothing on this earth more to be prized than true friendship.”

“Love is the evolution of true friendship. Любовь — эволюция настоящей дружбы.”

“Love demands infinitely less than friendship.”

“If you love someone but rarely make yourself available to him or her, that is not true love.”

“True love is rare, and it's the only thing that gives life real meaning.”
