Being or feeling alone is one of the saddest places to be. You can have all the money in the world but if you don't have anyone to share it with, you have nothing. The need for human companionship is universal. In ancient times, people stuck together because they literally needed each other to survive. In today's world, we tend to spread out and live more isolated lifestyles. In some ways this is a luxury. In other ways we had it better when we lived in close proximity. Humans are creatures of community and need each other for companionship.
