How can we make Teens stand out?

So many good ideas in this thread! I strongly agree with the teen specific traits, the specific clothes, the high school cliques, as well as the aspiration system @FanPhoria mentionned (I hope it's introduced in the university pack). Someone also mentionned specific interactions such as "sneak out", which I also think is a great idea.

I don't know if many will agree with this but I've always wanted to be able to go to school with my child/teenage sims, and since the Get to Work expansion pack I'm convinced that it could relatively easily be a thing. Especially since they gave us the choice to go to our Sims' workplace or send them alone from the very beginning.

I would also like more careers available for teenagers that wouldn't only be part time jobs, or opportunities (like being a teenage superstar or a scientific genius) that would include the possibility of leaving school to do something else, be homeschooled or go to a private boarding school like in the Sims 2.

But overall the simple fact of making teenagers very different from young adult is a great idea to me. Teenage years are usually full of crazy changes and identity related challenges, it would be a great thing to take advantage of that!
