One word...Feminism
Pretty much,
I used to say "yes ma'am", but two weeks in NY, and about a 100 "don't call me ma'am"s later i stopped.
Yup; feminism.
I'll help my girlfriend and my mother and sisters.
Women want equality right up until it's inconvenient for them.
They have the right to carry their own heavy bags, open their own doors, and drown, too.
