The first person who typed “should of” probably heard of it in real life that was meant to be “should’ve”, they typed “should of” online and readers thought that it’s grammatically correct to say “should of” which is in fact wrong and it became widespread throughout the years on Reddit.
I hope something could start to change.
House of Leaves is as much a puzzle as it is a book. I wrote in the margins A LOT as I was reading/solving it. FYI, there are more fake references than real references, but some of the references are real.
