Hell, I look at a 20 year old human as immature and I’m just in my thirties!

Biological maturity does not equal getting the life experience of an adult. Not enough life experience means more naive and easier to manipulate, even if the older being doesn’t want to.

That’s some shit and you should judge people by their character instead of their age. I’ve known people in their fifties and sixties who were less mature than other people I’ve known in their twenties, and we’re not dealing with developmental issues here.

Some people have gone through way too much shit by the time they hit twenty and have moved well past being “naive and easy to manipulate”. I say this having been one and married another.

Maybe the real “immature kid” is the one making ageist judgements on people who really aren’t that much younger than they are.
