Pet peeves: when someone is writing/speaking "Shakespearean" English and uses "thee/thou" for a second-person plural.
I'm sorry that it doesn't sound ye-olde-timey to the ear to use the word "you," but it's how it is. 🤷♀️
(For that matter, by the time we get to Shakespeare, people were already frequently using "you" for second-person singular, though it was more formal than "thou", so...)
