“There was a rumor that the loft storage area above the stage was haunted because a group of teachers came in after hours to pick up a forgotten item and heard a sharp "GET OUT."
They obviously thought it was students playing a prank but they checked every possible hiding place and no students were located. so the teachers assumed they imagined it and left.
Rumors spread that either there's a legit ghost in the auditorium or that, duh, it wasn't a ghost. And it was much more interesting to say something happened than to assume the teachers imagined a sound in a breezy auditorium. The most popular rumor was that two students were having sex and pretended to be ghosts to scare the teachers away.
It was half true. The students were boning in the loft and heard the teachers come in, so they hid under a pile of stage costumes. the "GET OUT" was because he was being a shithead and shoved his junk back into her junk while they were covered in nasty stage clothes. Yes they got UTIs.
I was the girl.”
