You know what they say ... " NO play makes slay gray . " OK I do n't think THEY say that , maybe its more like " No play makes slay even meaner . " Yeah I think that 's it . So I am looking at this cache , waiting to see who would find it first , checking it periodically during the day ... And no one claims it .

Question: What 's the likely reason that the narrator keeps checking on something ?
Answer: Out of curiosity .Out of boredom .He feels gray .He 's mean .
