Oh wait, no, there totally is a reason Foer’s new novel inspired this rumination on unrequited literary love. After Foer interviewed actress Natalie Portman in The New York Times, seemingly everyone remembered simultaneously that Foer’s marriage apparently collapsed because he fell in love with Portman while working with her on a film adaptation of his nonfiction book Eating Animals.

As far as cringe-worthy stories of unrequited love go, this one takes the cake.
