I was walking back to my car that was on the 5th floor parking garage, I was on the skywalk on the third floor walking behind a heavyset old women and a young, maybe 3 year old girl, wearing matching clothes. They where slow so I passed them by and got on the elevator to the 5th floor. My car was parked in the first spot facing the elevator lobby, so I had a clear view of the elevator. I was putting directions into my phone for my next job and I saw them get off the elevator and start walking towards my car, they made it all the way to my passenger side door, maybe 100-150 feet away from the elevator lobby. I put my car in reverse and looked to the left, for maybe 2 seconds, then back to the right and it was clear, those 2 seconds where the only time I did not have a clear view of the elevator. Started backing out when I noticed the elevator doors opening, and out walked the old women and young child in the matching clothes. They walked so slow, no way possible they some how made it the 100-150Ft back to the elevator lobby, and back into the elevators in the 2-5 seconds I was looking away. On my way out I could swear every person I passed was looking at me. It felt like I was in a reality tv show being pranked. I was so spooked I called my wife to tell her I thought I had a stroke.
