This look is all about being fed up but holding it in eyes narrowed, one brow raised, a hand on the hip, and a finger pointing like they’re ready to explain exactly why they’re annoyed. It’s the face someone makes when they’ve had enough, but they’re still trying to be polite. You’d use it when you’re halfway between a sigh and an outburst, like you’re saying, ‘I’m done, but I’ll wait.’
