[great comic, not such a great flick]
just one day can change everything
what does in fact change things? under same circunstances one person or thing can change and other doesn't. it's the mystery of diferential affectations. the unchanged can be a virtue in this story, but at the same time it just isn't funny.
all that matters for the physical world would seem to be functionality, but a tilted picture on the wall just doesn't comply to the same idea than a straight one. in art, every detail can be transformative. that which does not produce effect and/or affect perhaps is outside the realm of art.
