Example of my life: I have a 17-year-old sister. I think she is in the most inflated period of self-confidence. When she was 5 years old, she was very smart and always said something very Unpredictable. However, everyone forgave her. Why? Because social rules create her like that. RIght now, she is 17 years old, and she is in Treason period. She still always something which will make people angry and embarrassed. However, no one will forgive her anymore. Why? Because when she grow up, she is turning from child to adult. There is not necessary to have a quarrel with a child or fool besides a healthy adult. My sister is playing an adult role which is difference to child.I hope she can learn self fulfilling prophecy otherwise she will hard to survive in society
