Friendship is not something you can learn in college or some learning institution, no one knows how to become friends you just become but if you haven't learned the meaning of friendship you haven't learned anything
It is not merely true that a creed unites men. Nay, a difference of creed unites men - so long as it is a clear difference. A boundary unites. Many a magnanimous Moslem and chivalrous Crusader must have been nearer to each other, because they were both dogmatists, than any two agnostics. "I say God is One," and "I say God is One but also Three," that is the beginning of a good quarrelsome, manly friendship.
I know nothing which life has to offer so satisfying as the profound good understanding, which can subsist, after much exchange ofgood offices, between two virtuous men, each of whom is sure of himself, and sure of his friend. It is a happiness which postpones all other gratifications, and makes politics, and commerce, and churches, cheap.
If two friends ask you to judge a dispute, don't accept, because you will lose one friend; on the other hand, if two strangers come with the same request, accept because you will gain one friend.
