* Why is there so much material geared toward women to 'do this, do that' for a man?
This is the great question. It annoys the crap out of me to. I think it has to do with gender expectation and gender reality.
* Women are generally, by nature, nurturers and caregivers, and feel they must do it all.
Not by nature but by nurture. It is a gender role not a sex role.
But I agree. I think in this society there is still an underlying belief that if a single woman without husband and children, whether by choice or not, is to be pitied.
