Well psychologists say. That mentally retarded people do knowwhat the hell is happening. I say just put them in some sort of insitution. My friends aunt has... I am going to butcher this spelling. god I am not going to attempt it. Its a common sydrome. Skitos?? Anyway she constantly calls the cops saying that her neighbors are cutting off the heads of people and that their are vampires hiding in her attic. She will call my friends parents up saying "You killed mom, "I hope you're happy" even though their mother is still alive and well. So ya they dont know what the hell is happening
