That diagram reminds me of one I saw a couple of months ago that caused some drama as it was not known that two of the people in it were sexual... turns out they weren't but it caused drama for a bit while sorting it out.
I love how these diagrams tend to be about who is boinking who. The moment that the info was passed that they were in fact not having sex, and therefore not partners some how, meant that a whole chunk of people fell off the diagram and were not part of the constilation. Sex makes all the difference in these things it seems... regardless of saying it doesn't.
