So I have spent Several Years being utterly perplexed at the idea that it's impossible to put a corset on without help from a second person.

It has literally only just occurred to me that my complete bafflement on the topic might be because my shoulders are hypermobile.

Is-- is that it? Is that why there's this bizarre incomprehensible cultural meme that the only way you can possibly put a corset on solo is with the aid of a coathanger and a doorknob? ENLIGHTEN ME, INTERNET.

something I will probably want to think about some more--

More Than Two on poly and the prisoner's dilemma. I find it reassuring, which of course means that my immediate reaction is to declare that I'm exhibiting confirmation bias and should look at it harder to work out why it's wrong (and also I've got a vague sense that I've seen substantive criticism of MTT that I ought to be taking into acount?), but -- right, okay, models for interaction to think about.
