Maybe so, I aint holding convo's with youngin's anymore. They all annoy me to no ends
But the few I do talk to all seem very "carefree" and immature. I'm sure the 17 year old is checking in with rules and things where as the 24 has more freedom... but man when they open there mouth it all sounds quite similar. But you probably right too... Talking to anyone under 25 and they all seem come off the sameish now lol.
I also remember in high school having a couple early 20's subs

Basically it was like a teen watching a class full of teens then... I recall some of the stories and event's vividly
