Sterling Cooper anyone?

I think I want to start this post by saying that I am a generally happy, normal person. That being said.... I have a thing with personal space, my bubble, per se. If I don't know you or don't like you... you need to back away from the bubble. You need to especially not touch me. It seems to be amazing to me when people are oblivious to how close they are to someone and if it bothers them.

There is a new person at work that doesn't seem to get it. It just irks me. Getting up out of their chair to come over to you when you are speaking. Leaning over you when you are working. I mean they are definitely coming from the Don Draper school of business etiquette (by the way I am obsessed with this show) but let's get serious here, Yuck! Not really sure what to do to solve this predicament and also keep the workplace environment kosher. Hopefully there will be an update soon...
