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

A man's growth is seen in the successive choirs of his friends.

Friendship may, and often does, grow into love, but love never subsides into friendship.

Never have a companion that casts you in the shade.

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

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

Friendship is certainly the finest balm for the pangs of disappointed love.

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

Lots of people want to ride with you in the limo, but what you want is someone who will take the bus with you when the limo breaks down.

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