This sounds like you may be on the autism spectrum, possibly some form of Asperger's.
As to your comments one at +6 and one at -2, the +6 comment is a succinct reply that makes clear what might otherwise be difficult. The -2 comment is an answer but one that has no hope as phrased of enlightening the person you are talking to, which is why it then resulted in a subthread explaining what you had done. Your phrasing also wasn't helpful since the problem in question had multiple possible approaches and as you phrased it the other approach was wrong and yours was the only way.
I'm not sure that speculations about mental disorders are really called for based on these posts.

This post is part of the Rerunning the Sequences series, where we'll be going through Eliezer Yudkowsky's old posts in order so that people who are interested can (re-)read and discuss them. The previous post was Pascal's Mugging: Tiny Probabilities of Vast Utilities, and you can use the sequence_reruns tag or rss feed to follow the rest of the series.
