So Tifa literally stood all night over his bed in the office til' dawn waiting for an answer? That makes sense and requires the least assumptions?
I meant that Cloud's bed being the one that is in
his office doesn't actually require any round about assumptions. Cloud and Tifa definitely weren't sleeping in the same bed before Barrett left but Cloud moving from whatever bed he had after Barrett left into Tifa's is an assumption that we have no real indication of ever happening (other than Marlene got her own bed but that doesn't actually say anything about whether Cloud changed his sleeping arrangements as a result).
And for your example of another case when assumptions would be made, it seems more reasonable to me that Tifa, with issues on her mind walked into Cloud's office with a wish to speak, and spoke, rather than there was a significant shift in Cloud's sleeping arrangements which were never really hinted at, as far as I can tell. (Unless you perceive the "do you love me?" scene in itself as a hint but that comes down to each own's interpretation of it).
TheMadHatter said:
watch the love of her life sleep? I'd do that for the person I'd love...
And this. I find it hard to believe no one else has ever had the impulse to watch/be near their loved one while they sleep whether they were in the same bed, room or even house, especially if your relationship with them is worrying you.
It's not possible for Cloud to also have a bed in his study for when he comes in from deliveries late? Houses do sometimes have more than one bed.
Well of course, but it feels like an explanation that's, while reasonable, been made to support the 'Cloud and Tifa sleep in the same bed, or at least usally' idea. It's a greater assumption than 'Tifa waited in his room with something on her mind'.
Also notice how two rather large assumptions have been made for Cloud and Tifa sharing a bed as opposed to the one required during the "do you love me?" scene for Cloud sleeping in the bed seen in his office.
EDIT:
That does not satisfactorily account for all the known variables, such as the utter lack of amenities in the office, that it's always called the office, what Mako pointed out, etc.
I take the point but this is Cloud and he isn't the most expressive person. I doubt he has many personal possessions to make a typical looking bedroom. Although, modifications/tools for his bike (IIRC) are in the office along with pictures of his friends, family and so forth and these kinds of things Denzel has in his bedroom (minus the bike stuff).
Remember, Occam's razor isn't just 'the simplest', it's 'of all satisfactory explanations, favor the one with the fewest unknowns or assumptions'.
Well I believe that's what I've kept in mind. See above because I feel more assumptions are made for 'Cloud and Tifa share a bed' than 'Cloud has his own'. But if I've forgotten something I don't mind being pointed out on it.
I also have a feeling a 'couples always or nearly always share a bed' argument will come up which is fine but I am only inclined to think otherwise in Cloud and Tifa's case because of Cloud's bed in his office and how it'd be the simplest conclusion that he sleeps there (I believe).
