I picked no, but that's not entirely true. I prefer solitude the majority of the time. I don't want to be around people, or talk to people(except for my wife). I have friends, and when I feel like it I see them and talk to them. For the most part though, I much prefer to be alone. I am alone the vast majority of the day until my wife gets home from work around 9pm.

The reason it's not entirely true is because, even though I am always alone by my own choosing, and the majority of the time I enjoy it, there are times at which I start to feel lonely. Though even in the loneliness I am feeling, when I feel it, I still do not want to be around others. It's weird, I'm not quite sure how to explain it. I'll get lonely but still want to be alone.

EDIT: I can relate to the above posts as well where it was mentioned that they feel lonely when they are with people. When I am around people I often feel lonely, because I don't feel I relate to others, or understand them. That surely invites a certain lonely feeling within. It is that way except with the people I consider myself closest to, and even with them, sometimes I feel that way.
