...The automated doors were closing with that sound characteristic of pneumatic machinery when, through the walls and the windows, a man's voice still managed to make its way to the passengers' ears. It was some announcement, carried by that gray-ish air you usually find in old photographs, but the voice was too faint to make out the message. He managed to catch some o's with strange dots hovering over them, as well as some u's wearing the same hat and some beta's. The flash of a chill passed through his spine, but just for a second. He then decided to leave the voice where it was --in the past, one minute; two minutes ago--, and continue reading there where he was. In that seat on the train, in that gray, washed-out atmosphere with that strange smell of metal.
