I like to think of it as being a Lone Wolf.
I have never had a need for friends personally. I'm not bothered if I don't go out much. I'm more than happy with my own company. I go to the Cinema alone. I go up to London to watch Chelsea games on my own. I shop alone, I go to the gym on my own, I do most of my activities alone. People think that is weird and they often "feel sorry" for me. Why?
I'm not shy at all. I can talk to people, I just choose not to be around others. I prefer my own company. While I do have a few close friends, I rarely do anything more with them then go get drunk on the odd Friday night. I've had girlfriends, and successful long term relationships. I would say I am quite social if that makes sense. I initiate conversations with strangers and colleagues and am happy to have a conversation but when it comes to living life, I prefer to do it alone. I'm raising money at the moment to do a charity skydive next year...on my own. Why is it people think they should feel sorry for you if you prefer to live so introverted? My quality of life is excellent, I love my life and I don't see how having loads of friends would improve it.
Obviously when it comes to women I'm a little different. I find women a lot easier to be myself around and they generally accept me for being "a loner". I've actually had a lot of them say it's sexy.
TL;DR - I'm a normal healthy person with the ability to socialise and make friends but I choose not to, because I prefer to live life on my own and by my own rules.
Are you the same?
