Do you think I am rude to others?

I am a very high strung person overall. At work, most people think I am quiet. I mind my own business. I do my work. Occionally I will get up and chat with the others in my department. I think I am liked by many here at work. One of my co-workers is also a friend of mine. But sometimes people get on my nerves. Even my husband. I can't stand long-winded people. For instance, there are several people at work who will just walk up to my cubicle and stand there and wait for me to turn around and acknowledge that they're there. Sometimes I will speak and sometimes I will look at them like "What do you want?". It annoys me when they talk slowly and drag out something that should have taken them two minutes to say. I can't stand people who give too many details. Just get to the point! Also, people who update you on every little thing -- that annoys me. One of my co-workers will come to my desk and talk for 30 minutes to an hour, sometimes longer. It drives me nuts!
