me “that doesn’t make sense” you “it makes perfect sense! You’re an idiot”
Me “are you talking to me? It doesn’t make sense” you “you idiot, it makes sense! You’re so stupid” me “can you read that again?” You “ you’re so stupid! Just because it doesn’t make sense doesn’t mean it doesn’t make sense!”
