Humans are social creatures.
We need each other, be it for work, play or simply for companionship and friendship. I was thinking to myself today just how much the world has changed since our cave-dwelling ancestors walked on the surface of the Earth. We have distanced ourselves from fellow humans with technology. Fellow passengers on the buses would rather listen to their portable CD players or walkmans than to engage in a conversation with others. Take a walk in the parks and try to smile at a fellow jogger.
