People like to rank on the Myers-Briggs test a lot, and most of it is probably deserved, but taking one a few years ago really helped me. It identified me as a introvert. I never would have thought I was introverted–I’m friendly and can talk to anyone–but I do prefer to be by myself a lot of the time, and I don’t get off on social interaction. I guess I always thought there was something wrong with me because of that, but I now understand that it’s just the way I am.
Yep. More so now that I’ve got the annoying roommate from hell.
That’s exactly the way I am. I am often told I am friendly and I can start a conversation with just about anyone but I really prefer to be by myself. Well, as much by myself as I can get being married with two kids, that is.
I have two very close female friends that I talk to on a regular basis, I’m extremely close to my sister and mother, and I have a ton of online buddies. My husband and I go out with mutual friends sometimes, but IRL I much prefer spending time alone. Give me a good book, some good music on the stereo and leave me alone, and I’m set.

You are not alone.
My wife and I are just like you. We have no friends but are the best of friends to each other. We are always together… I’m retired, the only place I don’t go with my wife is to her hair dresser. That amounts to about an hour a week that we are apart. We both have no interest that the other doesn’t have.
I was pretty much a loner when we married but she wasn’t. But now she is just like me. 
I don’t know what either of us will do when we are left alone?:smack:
I generally have a lot of friends wherever I go but sometimes that starts to get on my nerves. When I have a lot on my mind or when my social calendar starts rivaling my professional calendar in the numbger of appts, I start coveting solitude. Occaisionally I escape to the beach but one of my favorites is to go to a large city (Paris, New York, DC) and spend time in a hotel and not talk to anyone. It probably sounds weird but I check in and other than hotel and wait staff I don’t call anyone, or do anything. I eat alone, walk around the city alone, go to galleries alone and it is absolutely WONDERFUL. I love to be lost in a crowd. After a few days I feel like my head clears and i go back to real life.
Thank you for the responses! I would have written sooner but I was busy being alone
It’s nice to know that I am not the only one who feels this way. For me, I think it stems a lot from shyness and as irishajo said, feeling like I am acting a lot of the time – playing the part of someone who is comfortable with chitting and chatting when I am not.
It is an interesting observation for me to have made about myself because I have spent a long time trying to work against the current, so to speak. I must say, it’s liberating to admit that maybe I’m just not cut out for casual friendships.
[Example] I lived on a cul-de-sac a few years ago in a very neighborly neighborhood. A lot of stay-at-home moms and children. (I do not have kids). I genuinely liked my neighbors a lot and would socialize at parties during the holidays, but I used to DREAD coming home from work. They would all be out talking and playing and I felt like the damn grinch if I just came home and drove directly into my garage [/end of example]. I did not peer out any windows, so I suppose that is a plus
