Adult mode is the mental state you switch into when life demands that you actually handle your business — filing taxes, having a difficult conversation, or choosing the salad without crying about it. It's a self-aware acknowledgement that you're consciously stepping out of your usual chaotic, fun-first energy and into calm, competent, responsible territory. The phrase carries gentle self-mockery: the fact that you have to announce you're entering adult mode implies you're not usually there. Think of it as the responsible alter ego that shows up when avoidance is no longer viable.
