when you're trying to tell someone something and they just keep yawning the whole time like you're boring them to death
You're mid-sentence explaining why your flight got delayed, and the other person yawns so wide you can see their back molars. You keep going—you're committed now—and they yawn again. So you speed up, which only makes you sound more deranged. By the end you're basically reciting your story like a hostage video, and they're still yawning, and you realize: they've won. They've turned your actual problem into proof that you *are* the problem.
