when i mean what i say:

if only; everyone sticks to their role and play them well.

if you are a mother, be a responsible and dutiful mother.
if you are a brother/sister, be a cheer and loving sister.
if you are a friend, be genuine.
if you are a lover, be trustworthy and dependent.
if you are a superior, behave like one and lead!

and the list goes,
the world will be a better place.

I'll sleep better at night!
