my problem with "tweens"

ngl here i saved myself like 1 year from being a gen alpha (shout out to my parents) but i currently have a 12 year old sister and the shit she talks abt is insane. 

one, shes obsessed w skincare. what the flip she literally has clear skin and is in 6th grade. then she tells me like drama at her school and its the most brutal and insane shit . she was telling me her bestfriend is getting bullied and teased because shes being a "pickme" then she proceeds to talk shit abt her. another day she said this boy ,a 11 year old boy, moved schools cuz kids in her school teased him for having a smal dick cuz ig his pics got leaked. WHAT THE FLIP!?so continuing on w this "culture" i think like these 9- 12 year olds have a thing for wanting to be older and i rlly hate it. i makes me sad yk? when i was around those ages i dont remember ANYONE trying to be older. closest thing i compare to this "tween era" to are the vsco girls w their sksksks. my sister dresses a lot older too, w her stupid flare jeans, areo postal shirt and a sweater. like she has absolutely NO graphic tees and gets so pissed at my mom if she gets clothes from walmart.( GANG I USED TO WEAR 24/7 THOSE SPONGEBOB RUGRATS POWERPUFF GIRLS SHIT IN 6TH AND 5TH GRADE😭😭)  she munches on takis and hot cheetos like every fucking day , blackmails me not the little oh im telling its a whole mafia type shit. then its not just her like her friends and other of my friends siblings. what is up w this? what is with parents allowing children live off tiktok? wtf is going on? me personally i dislike tiktok and refuse to download it because i think it's ruined a lot of things. i don't know i cant rlly do anything abt it but im actually scared the cringe culture will be dead. creepypastas, fnaf lore, MatPat, cartoon network, fanart, tim burton, invader zim, emo bands thats the stuff i was into in 6th grade, now its just like taylor swift, preppy, tiktok,skincare shit?  WHAT THE FLIP HAS HAPPENED?!
