Do think the teenager are different, than teenager 10yrs ago?

Teenagers are definitely more tech-savy today than 10 years ago. I may even go so far as to say that they are more advanced in their behaviours as well, but only superficially. I don't know if children are more emotionally mature than their counterparts of 10 years ago, but their dress, behaviour and attitudes are more "modern" or "adult-like" than previous generations.
