This could be from any age really. I remember reading lots of books like Harry Potter as a 4th grader to seem smart to the teachers looking at me but I didn’t understand any of it. When the big YA dystopian boom was happening, I read tons of terrible YA dystopias to seem cool but many of them frustrated me.
I got Karl Marx “The Capital” for Christmas when I was 15. Naturally I was (and still am) completely overwhelmed with its topic and content. I never progressed to more than 10 pages.
