It is often said that in prosperity we have many friends, but that we are usually neglected when things go badly. I disagree. Not only do malicious people flock about us in order to witness our ruin, but other unfortunates as well, who have been kept away by our happiness, and now feel close to us on account of our troubles. When Shelley was poor and unknown, he had more friends than the triumphant Lord Byron. It takes great nobility of soul to be able, without any taint of self-interest, to be friends with fortunate people.
