context: Yes , I had to stop often , but that was the plan all along - up 2 flights , stop and cool completely down ( read a page , maybe ) , fan myself madly , then up another couple of flights ... But even this trek was sort of fun because I wasn't alone . There were lots of people going up and down , and we traded'Where were you when ...'stories or'How far up are you going ?'stories .
question: Why was the trek sort of fun ?
reference: Because other people were doing it as well
candidate: It was fun because you were alone and didn't have any one to cheer you up.
