Were you guys actually stupid from 18-24 or is that a rhetorical device?

Every time I look up I see a comment like "at 23 I wore floatation devices to not drown in my soup, therefore anyone under 29 is a child".

When I was 20 I was making the exact adult decisions that lead to my comfort at 30. Therefore I assume every legal adult has some form of agency and people get mad at me for it. Even at 16 I remember thinking "alright its going to be time to quit fucking around and be serious soon here," or how today's generation may phrase it "time to lock in".

I'm so serious when I say I can't tell when you guys are just making some sort of point or if youre functionally braindead cadavers responding to local stimuli for the first three decades of your lives.

edit:

since Im going to bed and everyone's pissed at me for some reason, calling me arrogant or privileged-- I spent 18-24 in Flint, Michigan. Experienced crime, experience the water crisis, went to community college, had to take a gap year, worked to afford the rest of university, graduated in like 6 years but felt like an adult way before that. It's literally just about making decisions. Then I read real, actual posts like "Im 23 and my mom still schedules my doctor's appointment." Guys that is beyond the pale to me. I can not curve my brain to accept the is the average human experience.
