We are 'social animals'

As we go about our daily life, we come across different ideas, like the idea that we are 'social animals.' Initially we might think that these words do not carry a deep meaning, but if we look within, we will come to realize that we are indeed deeply interconnected with others. Our lives become less meaningful without others. Without others we are like a planet absent of a star. We often do not appreciate the importance of contact with others. I think because we are not often alone for extended periods of time, we do not understand why socialising is important. I once heard about a prisoner who was kept in solitary confinement, and he reported that this time spent alone had been the most painful time of his life. So, I personally feel that it is correct to think of ourselves as like animals who rely on the company of others for a happy and meaningful life.
