What’s the third sentence in a conversation that sticks with you?

I was just thinking about how often the third thing someone says—after the greeting and the first real thought—ends up being the one that shapes the whole exchange. Like, it’s not always profound, but it’s where they let their guard down. I keep wondering if that’s why I remember so many cockpit conversations: the third sentence after ‘Good morning’ or ‘We’re cleared for descent.’ Something real slipped out. What’s yours?
