I can only guess, lol.
To me, a normie little girl is susceptible to social hierarchy. That's where it starts. There's usually the popular girl and a bunch of other girls that look up to her. They like to role play the family, where of course, the popular one always gets the role she wants and others have to get satisfied with what is left, according to some internal popularity chart. Those other girls tend to simp to the popular one and compete with each other to be her best friend. They like to play with dolls because that's what girls are supposed to do and they are rewarded for it by adults, they are super susceptible to current ads, commercials and popular music, so you can guess that the popularity often has something to do with social status of their parents because the leader often owns the coolest and the most expensive dolls or cool toys. I'm talking about late 90s and early 2000s so no idea how it's today, lol. They probably have the biggest collection of Labubus and the newest CD (sorry some kind of VIP subscription) of Taylor Swift or something like that. Anything that gains general attraction and popularity.
As for boys, idk. Guess the same but their leader is good at sports or has the coolest collection of cars or pogs, pokemon cards, action figures (sorry, again 90s). 😆 Some stereotype like that.
So the girl becomes a teenager and the cattiness increases. Now the popular girl wears makeup and a bra she doesn't yet need but she wants to get the attention from the normie boys, especially the popular normie boy because she wouldn't be seen with some loser, right? Soon the normie girl finds out that alcohol is what brings people closer and which is the most efficient social glue, so the normies go out to drink and party every Friday and act like this is the coolest shit ever. The typical normie place is a party club with loud music or some popular bar where you're the most likely to meet people their age. The popularity status is losing the importance because now there are couples formed. Normie kids do their driver's licence as soon as possible. Their parents pick some college that is supposed to promise their normie kid a stable career, like pharmacy, accounting, business management or law and the normie kid has no objections. And off they go to colleges where they keep meeting on Fridays but now instead of clubs for teens they meet at fancy bars or organize private weekend parties at someone's place and drink less and less as they age. They get their degrees around the age of 24-25. Get a job right after because their normieness is exactly what recruiters are searching for, get married about 2-3 years later, have a kid next year. They participate in team buildings and are fluent in small talk, fake smiles and fake interest.
Okay, I got bored, sorry. Idk what else is there. 😆 They probably drive kids to work in the morning, work in some office filling out excel tables, brown nose the manager, engage in small talks and make stupid attempts at jokes with coworkers and another normie forcibly laughs, then they pick kids from kindergarten/school, go home, have a family dinner that the woman cooked, watch news in the evening, then go sleep or have standard heterosexual sex or something, idk.
