something i think about a lot is how, in the phoebe bridgers song "i know the end", she never actually sings the phrase "i know the end". there's the repeated "i know, i know, i know" after "so you had to go" and "so i gotta go", and then there's the very final, "i turned around, there was nothing there; yeah, i guess the end is here".
but it's "i guess the end." not "i know". and for years and years i thought about how incredibly satisfying it would be if she had changed that one word, if we did actually get the title in full right before that generational outro.
then today, i heard the song for the first time in a while, and it occured to me that maybe that's the point. because that's how endings often work: you realize them in retrospect. you see with painful clarity the things you would have changed.
