Annoying and rude co-worker (rant)

One of the paralegals at my office is so rude to me. For. No. Reason. When I first started here, she told me "I am old enough to be your mother, so I demand respect." I don't even remember what made her say that, but it was way out of line, regaurdless. She has even yelled at our younger attorneys a number of times, but the older attorneys let her get away with it. One of the young attorneys even quit becasue of it. I make her copies for her and she times me on how quickly I get them to her. Which is silly, because once I give them back to her, they sit on her desk for hours- literally- until she needs them. She constantly gossips about me to the assistant in the next cubicle too. She will walk by my cube (I am assuming she thinks she is being sneaky) and peek in here to see what I'm working on, and then walk into the next cube and start whispering. You aren't slick!!I know what you are doing in there! And the girl she is talking about me to has made it clear many times that she doesn't have time to sit and gossip. And now the paralegal is walking around the office with no shoes on! She has been doing it all week and it is GROSS and unprofessional- I know at least one of our clients have seen it. UGH!! I am ready for her to retire!!!!! /rant
