I thought like why couldn't he record the voice of the girl or open the door and check who's in the next bath room or take a pic or what ever. Well, isn't it easy to say these things. Just imagine yourself at a haunted place alone with no living creatures around you and suddenly you hear someone laugh just next to your door. Will you have the courage to open the room where you are and check it or will you wait in your room firmly closed for someone to come.
People bluntly say, Yah, I never saw a ghost and I'm waiting to see one, but what's their intention? Do they expect the ghosts to come out from these places and show them that they exist? Atleast they need to go to so called places and check themselves :)
