"It's not good for man to be alone." -God
It's all reflective of our need for community and the different forms in which we find it. It's not always perfect and it certainly never progresses exactly as we anticipate, but it's an essential part of our social development and it helps us maintain our connection to something that is real. We weren't meant to go through life alone and if we pay attention we'll see that we have more connections around us than we often realize.
