"I went to the lobby and asked Stan what he knew about the person who lived in 6A. He said 'Never seen anyone go in or come out. Just a lot of deliveries and a lot of trash.' 'Cool'. He leaned down and whispered 'Haunted'. I whispered back 'I don't believe in the paranormal'. He said 'Ghosts don't care if you believe in them'. I walked back up the steps, this time past our floor and to the sixth. There was a mat in front of the door which said 'welcome' in twelve different languages. That didn't seem like something a ghost would put in front of his apartment." -- Jonathan Safran Foer, Extremely Loud and Incredibly Close"
