How would you improve Teens?

I think the problem is that the teens...don’t feel like teens. Or feel like older teens/college students instead. They don’t look like teens and do the same things as adults with no milestones beyond maybe one crush thing (the rings) and making out action. Not much to differentiate them from adults, especially since they can wear lots of the same stuff and look fully grown like the young adults.

Homework helps, but we had proms and driving lessons in the past. I would like more teen stuff.

We need something that is in between the child and the college student.

Either that, or give the Young Adult stage something different that separates them from both the Teen stage and Adult stage. Those teen and up stages (until Elder) look almost identical to me.
