Just get Away
There is a lady that I work with that bothers me so much. While I am working on the computer it is nothing for her to come and stand directly behind me watching what I type. One of these days I would just love to send an email with her behind me stating something about how annoying I find it, but I just can not be that rude. I have just sat there before when she stands behind me, stopped working but she still never gets the hint.
