One interesting fact about Burroughs is that he was a chronic drug abuser and managed to shoot his wife during some sort of drug fueled accident. The message in this little piece can be easily interpreted as Burroughs trying to analyzing his own mistakes that lead to her death.
This is really just scratching the surface of how odd and complex Burroughs' life and psyche are. If you are a fan of surrealism, the beatnik movement or other larger than life writers like Hunter S Thomson, it's worth giving his work a chance.
