The Stanley Parable (Book edition)

All of his co-workers were gone. What could it mean? Stanley decided to go to the meeting room; perhaps he had simply missed a memo. The meeting room, yes, that's where everyone would be. Stanley just needed to get to the meeting room and from then on he would never be alone ever again.
'How long was I sitting there?', Stanley wondered to himself. Minutes? Days? Centuries? Did something crucial happen while my senses were turned? He made a note to be more careful with time from now on.
