Yeah, that's another difference - mine don't "make" me guess, because they're not really capable of that. They can't know anything that I don't know, and they can't keep secrets from me, because anything they know, I also know. (This is the whole "not a separate consciousness" part, I guess.) So when, for example, I'm arguing with one, and she's mad at me for not fixing a problem and I ask what I'm supposed to do about it and she says "you know what I want you to do", then if I don't actually know, it means she's bluffing and she doesn't know the answer either. It actually makes it easier to deal with her (I say "her" because there's one specific one who is most likely to do this), because normally I cower in front of her and believe every negative thing she says, and implicitly assume that she's right and I'm wrong; but if she's obviously trying to pretend to know something I don't, we both know full well that she's lying, and that's just kinda sad. That's one of the few times I can laugh at her. Each of mine has a role, but I wouldn't call it a purpose, because it's not exactly a function. On account of they don't help me function. In fact, in many ways, they are personifications of my lack of functioning. I didn't mean "trauma + already having subpersonalities -> DID/OSDD", just that the apparent human tendency to autopersonify might be a contributing factor. Kinda like... it's very common for humans to be comforted by familiarity in the form of routines; this is probably a factor in why OCD is a thing that can develop as a response to distress or anxiety. Does that make sense?
