Swing and a hit!

I don't like personal space invasion perpetrated by strangers or people I don't like. Of course, there are those who know this about me and will do it anyway because they know that I feel all violated and stuff and it's a great way for them to annoy me.  I've found a way to deal with it.
SPAZ OUT. Swing around with an elbow or whatever and done. A VERY nice personal space bubble can easily be created in a very short amount of time if you are marked as one who is going to swing.
If I have to be around people, I might as well make it a sport and make the rules my own, especially if I have to deal with people.... :s
