A man who was hopeless

I heard the story of two friends who were talking to each other. One remarked to his friend and said, “Man, you look so depressed. Whatever could you be thinking about to depress you so?” His friend quickly replied, “My future.” “Your future?” his friend said. Whatever in the world would make it so hopeless?” to which his miserable friend sighed and unhappily said “My past.” (Source unknown).
