something that might be of interest is that at one point I asked a number of my (genuinely lovely and welcoming of plurality) singlet friends if they'd ever thought they might be plural and if they'd ever want to be plural and their answers were overwhelmingly "not... really? I have never had a reason to?" and "actually becoming plural would mess with me a lot! plurality isn't a bad thing but I am personally very comfortable operating as one person and having to share my head would upend everything"
and these folks weren't like, Normies(tm) either! all of them are queer. most of them are trans. most of them are neurospicy. absolutely all of them have Beef With The World
this is, of course, not representative of everyone - like, some cis people question their gender and decide they're still cis, other cis people have literally never thought about it in their lives. but yeah, it's like... all human brains might have some level of inherent pluralness to them, but there are still people for whom plurality just doesn't fit, regardless! wondering if you're plural and/or wanting to be plural is not a universal experience, and it is worth exploring those feelings instead of brushing them off as "something everyone thinks at some point," even if in the end you decide that your answers lie somewhere other than plurality.
