Sample-of-size-1 statistics time (from which nothing can be learned, just for fun)? I (freelancer) once had a software-making client that employed me for a month do contribute a special component to their big project. When I arrived the big boss himself received me and showed me around - and when it came to showing me where and with whom I actually worked he apologized profusely before he even started. Apparently I had to work with the one (and only) guy who sat alone in his office. But he was the guy who had written the specs that I had to write the code for, and he had room since all offices were designed for at least 2 people. The apologies were because that was the most difficult person in the entire company to work with, by a margin, but he was too good so they just kept him in his cell... Well, I wasn't daunted at all actually. Turned out that yes, he was difficult socially. For example, there was a woman who came in to ask him something (it was rare anyone talked to him while I was there), and in an audibly annoyed tone he pointed out that he had already sent her that exact information 5 days earlier in document XYZ on page N, headline "3.2 foobar" (yes, to that detail, without looking anything up). He also was really, rally good. The specs he had written, several hundred pages in three documents, were near perfect. I didn't have to ask a single question at any time, he had thought of every detail. I myself also had no trouble talking to him, I had fun with the other people that I visited in their offices (who repeatedly told me pitied me for having to share an office with that guy), but also with my room mate. Because of the surrounding highly unusual circumstances this still is one of my most memorable (and completely positive) freelancer jobs.
