Freaked out by a Stalker?

I was at the Walmart a few days ago trying to make copies of Amanda's Christmas pictures, and knew other people perhaps were waiting, so I was trying to get finished quickly. Now, I didn't want to turn around and look at the people standing behind me as if to say "ha, I'm before you...just wait" (really, I would never do that), but out of the corner of my eye I could see a customer moving back and forth. I thought to myself, "can't the person be patient". I continued with what I was doing and still out of the corner of my eye I could see this person, and they seemed to be getting closer to me. Scary! The next thing I knew, the person jumped at me, I got startled, and it was then I realized it was the "girl" on the HP Kiosk next to me...oh well, got a good laugh about it later :)
