Is it just me?

This is going to be very random but I have a quick story. I left work tonight and went to Walmart to get Roderick some hair gel and etc. I was so worn out from this sinus infection and just really wanted to get home. I searched for a line and parked and waited. Then an older man came behind me in line with a small purchase (poker cards, magnifying glasses, and some tic tacs I do believe...aren't you glad that I am so nosey?). Here is the part that I want to know. Do you have a problem when people invade your space? I call it "invading my space bubble". Does anyone else call it that? Like the invisible bubble around you that says you can come this farther and no more...like some inch boundaries. So, I kid you not I waited in line with this man behind me for AT LEAST 20 minutes. Every time I moved back to give him the signal that he was a space invader he inched closer. He was literally like an inch from me at all times. I began to have a little fear over this and thought maybe I was just being paranoid and that I might need to put my hand on my glock just in case (I am kidding). I pretty much thought he was about to jump in my shopping cart (a.k.a. buggy). I said goodbye and told him I was glad he got a new heart and some kidneys and ran like mad to my car. It was a strange time. Do you have "space bubble issues" and struggle with close talkers?

ps Faith just reminded me to put this...i don't have the space bubble issues with people that are family, friends, and etc...just strangers.
