@Lucy,
I don't generally like stereo-typing, becuase it's usually used in hurtful ways.
But I would venture to guess that many of us have some form of difficulty when it comes to personal relations. I don't want to put all of us in that box, but in my experience programmers and artists alike usually have some quirks when it comes to person-to-person communication.
I'm not so introverted or anything, but I do have my moments. What I find in my life, is that I'm not always able to relate to people, or they just don't get me at times.
I have a hard time reading body language (when I am excited about a topic), and I genereally don't recognize when people think I'm talking too much, too fast, or in circles. Or if I do recognize it, I guess getting my idea out becomes more important than what I think the other person is trying to tell me.
I also find that I tend to over analyze things, and I find my reasoning leans towards the logical rather than the emotional side.
I also have a hard time of getting directly to the point. I tend to like language, and my own way of discussing something. I give a lot of background, I weave my explanations and don't stick to a linear time-line; rather I jump all around and then finally (try to) tie everything together.
Perhaps I like my own voice, or typing. To me it's interesting. Others can find it annoying. Sometimes I am overly verbose. I love using analogies, and tend to give 5 different angles of looking at something (even if the person understood me the first time).
I can easily get frustrated if someone doesn't follow what I am saying. And a lot of times my way of talking gets mixed up with people thinking I am trying to be a "know it all". I just like offering my views, and I like friendly debate. Their are occasions though that I can go over the top. When I calm down and re-read or rethink my actions, I can be overcome with a feeling of guilt.
I've tried to come to terms with my personal quirks, and embrace them. I also have to recognize when and where I need to filter myself a bit. Like now, LOL, I think this post grew longer than anticipated. So time to close my pie-hole!
