When I was a teenager, I felt I was so lost and wanted to prove that I was mature enough to get rid of my parents' nursing.
That happens to most teenagers, they are under the stage that is close to mature but are not strong enough.
For parents and teachers, they must deal with teenagers' change in the right way, or they will do the negative things.
There are many reasons for teenagers' change.
First, their bodies grow so fast that they could not adjust their mood.
The change in their bodies makes them feel different from others, they don't know how to do, so they feel annoyed and want to disguise themselves.
For parents, they have to realize that their kids have grown up and should not treat them like a kid.
Second, the parents must get to know that the teenagers will experience many stages during their teenager time.
So when their kids become rebel, they need to understand and not fight with them.
Giving their kids some time, they will overcome their emotion.
Teenager time a special stage, the change of teenagers will make the parents and teachers worry,
but I think they should not be so hard on them, just to be their friends.
