The Weaker Sex -- Really?

Females seem to be born with "service"writ on them,
Service not "servitude" as many like to assume
For
Your baby brightens up your day with her toothless grin,  

Your youngster obeys your rules though she may frown, 

As a bride she makes you proud leaving you with a heavy heart,
A sister is your tiny mother,who takes your rap,

A mother nurtures,loves & lives her life according to your whims,

Bearing the greatest pain known so you can see the world,
A wife forgoes everything & everyone to support & be your side-kick,

Grand-ma is a sanctuary you know as your birth-right,

All this in silence while bearing your brunt,
I would like you to tell me what the above is

A Superwoman or The Weaker Sex??
