>If she says, "I'm going to Hawaii for vacation," it's not asking which island or deep details. It's saying, "That sounds nice." You care but you don't really care. You're emotionally detached. That's not really "emotional detachment", though. It's not very different from actually running away the moment you see her, it's just less obviously cowardly. If you were really emotionally detached you would ask for as much detail as you could and it wouldn't affect you in the least. Incidentally, not asking any follow-up questions to such an announcement is an obvious sign of disinterest. It's just a more polite "I don't care in the least about this thing you're telling me and I don't want to hear any more about it". Everyone knows you're doing it because that's exactly what they say when they don't want to hear about some topic.
