Well, in the offline world, only my Mother and my brother know(^our father does not, because ^we know he'd react very badly). They both reacted... okay at the time, I think, but gradually they've started to treat ^us like a singlet, and they are mostly ignoring the way ^we are. The rest of ^our offline family/friends do not know, and ^we don't really feel the need to tell them. Online, the only people who know, pretty much, are those ^we know are okay with healthy multiplicity (both multiples and singlets).
