In these days,the little kids have few homeworks,few lessons and a lot of energy and free time.But,the teenagers have a lot of homeworks,a lot of lessons,and few energy and free time.
The teachers and parents don't understand what a big preasure they have to carry daily.They have to think all the time about how they look,especially girls, because at this age they see them uglyier than they really are,and a lot of pressure from lessons,homeworks,and parents,what don't understand them.
At school,they always don't understand anything,but they still silent,because they are scared about what the teachers would say about them or what would the others think about them.
At school,there isn't only about study,but about your look,your kind of phone,and how popular and cool you are.
If you don't have a phone,you're strange.If you're not populat and cool,you're strange.If you like to study,and don't like to hang out,you're a jerk again.
So,you have to choose rom popularity and success in life.
This is why teenagers are under stress.
