Friendship is always a sweet responsibility, never an opportunity.

Friends show their love in times of trouble, not in happiness.

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

Silences make the real conversations between friends. Not the saying but the never needing to say is what counts.

Men kick friendship around like a football, but it doesn't seem to crack. Women treat it like glass and it goes to pieces.

Never explain - your friends do not need it and your enemies will not believe you anyway.

A friend may well be reckoned the masterpiece of nature.

Friendship without self-interest is one of the rare and beautiful things of life.

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