When do you become an adult?

AUGUST 28, 2016 

You know you hear people saying "Act like an adult." ...I wonder..When does one become an adult? Sure we all know the legal age...but you must have noticed how even "adults" love to remain a child at heart. Is it taking up of responsibility that classify s one as an adult? What if someone does the things they are responsible for and still has the personality of a child? Does that mean they are dis-functional? Many adults forsake all childish things and involve themselves in issues of society, economy, politics. Is that being an adult? or just personal interest? What of those who don't indulge or know of such things but contribute to the world in their own way? Who is to define it? Is it not okay if the person has it in a balance?
