A man should always try to develop his acquaintanceship into friendship, at least where it is possible; but where it is impossible he should try at least to continue acquaintance, instead of going from acquaintance to estrangement. A man always wonders how he can make friends with everybody, for friendship is such a rare thing; and so he waits with his high ideal perhaps all his life, and does not meet his ideal friend. And as he passes by all those with whom he becomes acquainted, in a way he avoids the chance of friendship with them, thinking they are not worth it. It is easy for anyone to say about another that he is not worth making friends with; but he does not know how much he is worth himself.
