The floor is always, always empty after 9:00 pm, yet all of the hard-working, or stranger GSE employees who keep late hours know of this phenomenon and have pretty much just accepted it. One staff member told me that she heard these noises while working late one night and she wound up catching a faculty member who was leaving his office and asked him about it. He replied "I have been hearing those noises for years. I guess the ghosts are pretty lively, ha ha."
Ha-ha, indeed. Is there an illegal late-night day-care facility being run on the third floor? Are four pale, beautiful, blond children locked up there committing incestuous deeds? Are there some pretty fiesty bats duking it out with giant albino rats on the third floor?
In the name of The Truth, I will bravely attempt to get an actual audio recording of these "noises".
