I've heard people talk about this at school so I decided to do a google search. Here is what I found:
A young boy locked himself in the basement of the middle school.
He sat in the middle of the room, in a wooden school chair.
While sitting, the boy cut his own throat, and died in that basement.
People say if you go into the basement at night,
you will see the chair placed in the center of the room,
and hear the boy whispering " get out." - Source: theshadowlands.net
If you have any more information on whatever the hell this is about, please comment.
