I've known LSE's and LIE's who've apparently been unaware of the time that various tasks can take.
The LSE thinks that other people should be able to have things done 5 minutes ago (perhaps basing it on their own ability to understand the 'logical logistics'), and with the LIE it can result from an un-appreciation of the details of something, sometimes avoiding them like the plague.
Unless i'm missing something, Ryu, imf and myself are saying similar things here.
Except, can you clarify what you mean by XLI being good at following? Taken literally, this does not make sense, SLI's are probably the most independent type in the socion, although I think you are hinting at something else?
