When teenagers grow older，they try to understand who they are．They are no longer children．Children start changing their clothing styles，hobbies，interests and friends when they began to understand who they are．
Teenagers begin to understand the world around them．They no longer just listen to their parents．They start to find answers themselves．And they want to go against the rules set by their parents and teachers．
Sometimes they are also confused（困惑的） about themselves．They are unable to make their own choices and decisions in life like adults．But they are not really children who fully depend on others for their lives．
During this time，teenagers still need help．They need to have a good relationship with their parents，not just be told what to do or not to do．They need encouragement（鼓励） to go for their own dreams and talents．They need more room and freedom to make decisions
themselves．However，the freedom needs boundaries（界限）．They need someone in their life that can encourage and cheer them up when they have difficulties．
