A friend
Welded into our life is more to us
Than twice five thousand kinsmen, one in blood.

Euripides

I used to think that friendship meant happiness: I have learnt that it means discipline.

Anna R. Brown

Dear is my friend—yet from my foe, as from my friend comes good:
My friend shows what I can do, and my foe what I should.

Schiller

We can live without a brother, but not without a friend.

German Proverb

Love is flower-like;
Friendship is like a sheltering tree.
