Lol to people believing that poltergeists just like pushing stuff and swiveling on chairs. Ever since the first lot of vids claiming to be paranormal activity cropped up, every video shows the same sort of stuff. No human interaction, no writing on the walls, just some moving stuff. Its all pretty tame really, no emotion or anything resembling trying to get a message/emotion across, just the image of some bored poltergeist thinking 'quick hes back with his camera....hmmm... ah theres a bucket, ill roll it once or twice and maybe flick a small nail across the room, thatll show him!'
