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

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

The greatest gift of life is friendship, and I have received it.

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

If you have one true friend you have more than your share.

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.

Never have a companion that casts you in the shade.

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

As iron sharpens iron, so a friend sharpens a friend.

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