I’ve read three of them. The headline is a bit misleading though. You’re not undateable if you’ve read these books, it’s only if you list them as your favorite. While I still think that is a bit overly harsh, I do agree with the sentiment that if a favorite book hasn’t been read since high school, chances are that person is not actually a reader.
That being said, I’m due for a re-read of “The Master and Margarita” and “Wuthering Heights”.
