I guess personalities aren't really hard-coded, they kind of develop based on the people you hang out with. And since there are a bunch of twins who kinda get bored because they're with each-other so much, they kind of branch out and make new friends who are extroverts or introverts, or they end up having the exact same personality if they end up staying together the whole time (but generally they split up siblings into different classes, so even that is unlikely). Idk, it's weird lol

And I guess even parents probably treat the kids slightly differently from each-other, just so they can each get their own alone time and stuff, so they're never growing up in the exact same environment.
