i never really realized this until recently
when I'm writing something I feel like I can 'read' a sentence like a new reader especially if I look at the draft after a while. but if there's a quote of something I've heard (song, speech, joke, etc.)→
it's difficult for me to 'read' it the way an uninitiated reader would read the quote (which can really make the quote seem better in your head than in a random reader's head)
I bet this is a well defined cross-disciplinary problem, especially in design right? Like if you've worked on a subway map for 5 years you can't really tell what a random person looking at it for 5 seconds actually 'sees'
