If Montressor had met Fortunato during the day instead of at dusk, what is the outcome that would result from a change in setting?

The main thing I think would happen here is that the whole
story would feel less foreboding and spooky.  I think that if the two of them had met in
the middle of the day, it would have not felt like something bad was about to happen --
at least not so much.  Even though bad stuff can happen in broad daylight, we tend to be
afraid of the dark just because it seems spooky.  That is, I think, what the difference
would be.

I suppose that you could argue that if it had
been the middle of the day, maybe Fortunato would not have been so drunk.  Maybe if he
had been sober, Montresor would not have been able to trick him so easily.  To me, this
is the main possible reason for a totally different ending to the story.  However, it
was carnival time and Fortunato could have been drunk at any time of the day seeing as
how he seemed to like to drink a bunch.
