For years, my biggest pet peeve was when people would retort, “True.” That’s just so obnoxious to me, like they’re validating what you say because obviously it might not have been true! Thank you for acknowledging that my statement wasn’t false. I know it’s a silly thing to get miffed over but it was mine.
Now it’s when people say, “I’m confused.” The thing is, they don’t say it when they are really confused; they say it when you say something against whatever they consider the “truth”—there’s that “true” element again!—and they disagree with it. “I’m confused,” a mom will tell me when I tell her of a special running at a venue she previously thought was closed or something. “I’m confused,” a relative will say when I tell them no, we didn’t go to X because we went to Y instead, even though we said we might go to Y the day before. (That’s irritating, too—when people act offended that you change your plans even when they aren’t involved in them.)
You are not confused. You’re just obnoxious. Why can’t you just say, “Oh, I thought X,” instead of whining, “I’m confused!” Save it for calculus questions, sweetheart.
