There are a couple of lovely quotes on the site, some of my favourites are:
"Each friend represents a world in us, a world possibly not born until they arrive, and it is only by this meeting that a new world is born."
Friendship Day Quotes by: Anais Nin
"Two are better than one; because they have a good reward for their labour. For if they fall, the one will lift up his fellow: but woe to him that is alone when he falleth; for he hath not another to help him up."
Friendship Day Quotes by: Bible: Ecclesiastes
"Friendship is unnecessary, like philosophy, like art... It has no survival value; rather is one of those things that give value to survival."
Friendship Day Quotes by: C. S. Lewis
