Stop Hovering

I want to put something out there that has been bothering me for a LONG time. While I'm at work, If I wanted to make conversation with someone, I would normally continue the current conversation we would be having. I would stop what I was doing and pay attention. I would even invite you to sit down cause I have a chair in my cubby space. But if I don't do any of these things, and I don't even look at you while you are speaking to me and yet you insist on hovering over me and keep having a unilateral conversation? Take a hint. I DON'T WANT TO TALK TO YOU!!!!
