Many years ago, in Jerry Pournelle’s novel “Janissaries” he had the character of Gwen think that love didn’t exist. All the poems and such about it were probably written by people who thought such feelings ought to exist but they hadn’t really hadn’t really experienced it.
In darker moments (which came quite frequently back in the day), long before I’d read that book I would say “Love isn’t real. It’s just something invented so that Belinda Carlisle would have something to sing about.”
(Given the subject and tone of the song this video is a bit…strange)
