Community

Human beings are social creatures. Even the most introverted people need interactions with other people. Some people try to substitute the companionship of a pet with human to human communication. Each of us know of people who don't like people. On television or in the movies. Even in our personal lives.
The question is why is human connection so critical to our experience? The primary reason is that most of us rely on a person or group of people for our existence. Even if we live alone with twenty cats we have to go to the grocery store and buy them food. We take them to the veterinarian and other places that cats go. I am part of Facebook groups and other Internet websites that promote community with other people. The thing that I like is that it doesn't require verbal communication. It's all written. I like writing. It's what I do.
Even as a child I would write girls that I had a crush on. Times were different then. There was no Call Waiting so after a while your parents would pick up the extension and embarrass you by announcing that they needed to use the phone. The other challenge was long distance relationships. I had a crush on a girl who lived in Tucson, Arizona. Long distance calls were very expensive and the least expensive way to communicate was to write. This was before the Internet, so there was no email, Facebook or Instant Messaging. You had to write an actual letter. Place a postage stamp on the envelope and mail it. You would hope that your letter would go out in today's mail and wait.
