That is one question I've always wanted to know!
Thankfully ever since we shifted to Australia and having no servants here or anything - my Dad and brother help out with the chores of the house.
I hate the fact that the girl is to help out in the kitchen, or serve the food when guests arrive.
Hopefully when I'll have my children, I'll try to keep these gender differences to an absolute minimum.
I would also like to point out that my family is way better than some other families I have seen where sexism is really obvious. Some examples include:
1) It's okay for the man to drink, and get drunk, but not okay for the woman to do so.
2) When guests arrive, the woman is to be in the kitchen, serving around food, helping lay out the dishes, do the dishes afterwards etc
3) Cleaning, mostly women do
4) Okay for boys to have girlfriends, but not okay for girls to have boyfriends.
These are just a handful of things I see around me.
