Be slow to fall into friendship but when thou art in, continue firm and constant.

A quarrel between friends, when made up, adds a new tie to friendship.

It is not so much our friends' help that helps us, as the confidence of their help.

That friendship will not continue to the end which is begun for an end.

A true friend is someone who is there for you when he'd rather be anywhere else.

When the world is so complicated, the simple gift of friendship is within all of our hands.

Nothing but heaven itself is better than a friend who is really a friend.

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

Never make friends with people who are above or below you in status. Such friendships will never give you any happiness.

Caring for but never trying to own may be a further way to define friendship.
