No, older women do know yeah but most of the girls (under 18) actually don't know these things nowadays it always depends on their mother or they can learn by themselves. To be honest, boys who are under 18, know better how to cook, how to do ironing etc. No girls aren't ready for take care of their family straight after the school. In my country, Marriage isn't that popular at young age. but i like your perspective tho.
