Real friendship, like real poetry, is extremely rare - and precious as a pearl.

So long as the memory of certain beloved friends lives in my heart, I shall say that life is good.

Friendship is always a sweet responsibility, never an opportunity.

Be courteous to all, but intimate with few, and let those few be well tried before you give them your confidence.

Never have a companion that casts you in the shade.

Nothing so fortifies a friendship as a belief on the part of one friend that he is superior to the other.

Friendship is a strong and habitual inclination in two persons to promote the good and happiness of one another.

Friendship is the shadow of the evening, which increases with the setting sun of life.

Even where friendship is concerned, it takes me a long time to trust people.

I value the friend who for me finds time on his calendar, but I cherish the friend who for me does not consult his calendar.
