I'm that person who points out all the grammar and spelling mistakes. Yup. Some people love me here at work. Some...not so much.
I can't help it. There is nothing I hate more than people using "I" incorrectly. You don't say "Do you want to go to the store with Tony and I?" It's "Tony and me!" UG! And the worst part is the wrong usage has become prevalent throughout media: tv shows, movies, even news articles! (omg, don't get me started!)
My second pet peeve is the overuse of apostrophes. You have no idea how hard it is for me not to correct my friends' posts on Facebook. No. Idea.
Just in case you need a refresher, the definition of apostrophe is: a punctuation mark ( ’ ) used to indicate either 1) possession (e.g., Harry's book; boys' coats) or 2) the omission of letters or numbers (e.g., can't; he's; class of ’99).
So this guy, "the Banksy of Punctuation," has become my hero!
