Its not like anyone care about the rules of grammar no more, so Grammar: Know Your Shit or Know You're Shit is really just a weak attempt to belittle and bully today's generation into going back a hundred years to learn a fat wad of archaic, prescriptive BS when all we really want to do is...go back three thousand years and talk in emojis, our updated version of hieroglyphics.
But I guess for the...whatever came after the dinosaurs, which would be more analogous to hieroglyphics, but are still dying like the Queen's English...for the post-dinosaur-but-still-old-as-crap grammar nerds out there, Grammar: Know Your Shit or Know You're Shit will be a fun Friday night read. Especially the parts where you can chuckle that you know it's "Call me, Bitch" but so many idiots out there write, "Call me Bitch." (Yellow heart, yellow heart, yellow heart, hand with thumb and pinky finger extended, pizza, taco, wine glass.)
OK, really grammar holdout Joanne Adams wrote Grammar: Know Your Shit or Know You're Shit as a lighthearted guide to speaking, scribbling, and typing correctly. Not to judge or badger you. The book includes common misspellings, a punctuation crash course, and tips on how to apply the right tense.
