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

You can always tell a real friend: when you've made a fool of yourself he doesn't feel you've done a permanent job.

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

Since there is nothing so well worth having as friends, never lose a chance to make them.

No person is your friend who demands your silence, or denies your right to grow.

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

There are no rules for friendship. It must be left to itself. We cannot force it any more than love.

Friendship... is not something you learn in school. But if you haven't learned the meaning of friendship, you really haven't learned anything.

In friendship as well as love, ignorance very often contributes more to our happiness than knowledge.

Without wearing any mask we are conscious of, we have a special face for each friend.
