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

Rejoicing in our joy, not suffering over our suffering, makes someone a friend.

The sincere friends of this world are as ship lights in the stormiest of nights.

Never have a companion that casts you in the shade.

Friendship improves happiness and abates misery, by the doubling of our joy and the dividing of our grief.

It is only the great hearted who can be true friends. The mean and cowardly, Can never know what true friendship means.

Am I not destroying my enemies when I make friends of them?

He has no enemies, but is intensely disliked by his friends.

Friendship, like the immortality of the soul, is too good to be believed.

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.
