Acronym confusion.

Back with the recent global warming talks, I thought like I always do that the COP 26 or whatever talks were the continuation of some agreement that had originally started in "Cop"-enhagen, when I read that the COP acronym actually stands for "conference of parties." But, even after I read that, I'd see the acronym and still automatically think that it meant Copenhagen. Part of me thinks that that's because maybe it's a bit of long-standing habit, but more probably because "Copenhagen" seems like a more natural fit for "COP" than the otherwise-weird phrase "conference of parties," which you never really hear anywhere else. So, even now, when I read a phrase like "COP 26," I automatically think of Copenhagen.
