I suppose I do relate to 5's detachedness and the need to become more involved in the world, but that's probably because I happen to be a recluse (which 4's can be as well). Maybe it would have to do more with why I'm a recluse. At this point I'm not really sure why I don't seek social interaction. Probably because it's easier to just sit in my room and post on forums all day. Maybe also because whenever I do socialize, I'm never able to express myself as well as I wish I could, which leaves me feeling disappointed and dissatisfied.
I'm not really sure whether this would indicate either type, since I could see both types wishing they could express themselves better and becoming recluses.
