Did the two friends know the password, and does knowing the password or not knowing it impact any part of Maupassant's message(s)?
Look back at the text and decide if they knew it or not first. Then examine if and how the story would be different with each scenario.
Actually, the two friends know the pass word.
According to my thought, I assumed either knowing or not won't effect the story cuz that mainly talks about the characters personality.
