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

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

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

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

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

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.

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.

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

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

Friendship with ones self is all important, because without it one cannot be friends with anyone else in the world.
