Ever Get The Feeling Your Being Watched?

So I arrived at work this morning around 6:50 AM or so, and on Mondays I am the only one in the depot until 8:00. When I pulled into the back parking lot there was this man sitting in his car...just staring at me! He kept staring at me as I pulled into my parking space. and I could see him in my review mirror still watching me all the time I was getting my stuff situated and while digging through my bag to find the key code to the back door. So I jumped out of the truck, punched in the code and flew inside the door. Trying to convince myself I was just being paranoid I continued opening up the depot, but I kept all the doors locked just in case. Well about five minutes later guess what I hear! Somebody was trying to get in through the back door! There was no mistaking it. I knew it wasn't an employee because they would have the key code, and it couldn't have been a customer because who would come in from the back with no signs and when it is obviously not an entrance. Well whoever it was did not come around to the front and try to get into those doors. Thank goodness they didn't because the front doors are glass and it would have been really scary/ awkward if we could see each other while he was trying to get in and me not opening the door to let him in because I was too terrified to assume he was a normal customer. Well I was extremely frightened and freaked out...but I'm alive! No creeper got to me today!
