Oh wow I read this in college years ago for a literature course. Was one of the less weird books I read in that course tbh.

Lol. I'm Dutch and had to read Dutch, English and German literature in high school. Here's how I would summarise the literature from those countries 

Dutch: Boring shit. Way too many old men fantasising about sex

English: Good shit. World famous books for a reason

German: wtf.... Are you guys okay?
