a little weird...

so...I had to go to the second floor today and make some colored copies. I had to make two ventures because we have these new copy machines that are like robots. No joke! Anyway... as I approach the elevator the door automatically opened, with no one inside and no one around either. Do I have an invisible door man? haha I didn't think anything of it at first, until I walked up the second time and it happened again! Weird huh. Ya I thought so too!
