Am I still a child or am I mature?

Well I don't know. I feel matured but I act like a child .I am also treated like an adult by my parents and also my teachers.To me I must be mature because its part of growing up.My life is starting to be hard so being mature I could cross all the hurdles in my life.If I am childish in this age which is 11, I am in trouble!So to my friends and classmates,especially Eng Hong, GROW UP!
