theres a saying that goes
"if you are calling everyone an asshole, maybe you are the asshole". i think we can replace asshole with liar. or maybe not.
The exact phrase is "If you run into an asshole in the morning, you ran into an asshole. If you run into assholes all day, youre the asshole."
That equally applies to the prick. The whole world is an asshole from Garza's perspective. Nothing wrong with him at all.
