Does your school have a background history?

well im in 8th grade. and people say my school is haunted. Well they all say that a lunch lady was having a affair with the principle and her husband found out and so she goes in the little kids bathroom and hangs her self... Then other are that its built on top of a graveyard. and that a teacher was murdered in room 203... and students say they see the rehappening of the shooting if you go in there. me myself i dont believe them...
