Just thinking of these last night. They tend to disconnect people from the conversation. Can you think of any others?
Habitually starting sentences with “No,” or “No way,” even when you’re agreeing or the sentence isn’t subject to agreement or disagreement.
“Shut up,” when said as, “You’re kidding!” This one’s tough for me.
Saying, “You have no idea,” or “You don’t even know.” This one is particularly bad. It’s mostly intended as something like, “The situation I’m referring to was really bad/good,” but it comes across as, “I have experiences you could never dream about.” Makes you sound super arrogant.
