Maturity
Many young people mistook Maturity for being aged, many people thought that once you are advanced in age, you are Matured.
Maturity weighs beyond being advanced in age, in some ways, it doesn't have to do with age at all.
I have seen old people exhibit a childish behavior and I have also seen a child act like an adult.
Hence, being matured is when one seems to comprehend or deal fairly with a complicated situation.
Why Do You Think Old People Act Immatured Sometimes????
