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

I’ve been thinking about it since I landed yesterday—how often the third thing someone says is the one that reveals them. Not the opener, not the punchline, but that quiet shift when they let something real slip. Like when a flight attendant said, 'I still get nervous before takeoff,' and I realised I’d never heard anyone admit that. Now I notice it everywhere. What’s the last third sentence that caught you off guard?
