It is necessary for man to distinguish between the friends who are true and who are not. Man needs friends to exchange his views and thoughts, hopes and desires sorrows and joys. So he mixes with others. But the persons with whom he develops intimacy and shares the feelings are not always real friends. When he has wealth and power, many people gather around him to praise and flatter. They are quite anxious about pleasing him. They do all these things with a motive of satisfying their self-interest. Man also thinks them to be real friends and help them. But whenever these days of prosperity are gone and he is in trouble, they desert him altogether. These fair-weather friends leave him alone. They no more stand by him in his evil days. They cannot be true friends, because a true friendship is he who is with him through thick and thin and becomes helpful in need. The test of real friends comes only in misfortune.
