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.

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

Am I not destroying my enemies when I make friends of them?

Friendship at first sight, like love at first sight, is said to be the only truth.

There is some self-interest behind every friendship. There is no friendship without self-interests. This is a bitter truth.

Friendship, like the immortality of the soul, is too good to be believed.

The sincere friends of this world are as ship lights in the stormiest of nights.

Instead of loving your enemies - treat your friends a little better.

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

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