There's never been any need to talk about those things in our house, we just do them. If a man and woman have to sit down and have big discussions about it they really shouldn't be together. If I come home and my wife is doing homework with my son, well...I break out with pots and pans and start cooking dinner. If I get home late with bags of groceries, SHE cooks dinner. If needs to go shopping, boy stays with me. If the dryer stops working, I fix it. If I'm at work and it acts up, SHE tries her hand at fixing it. I do the heavier yardwork because I weigh 1.8x as much and am 10" taller. And sometimes we put the boy to work too!...because boys AND girls need to learn how to work and earn things.
There has never been any need for us to talk about WHO exactly should do these things. We both have day jobs, a son, and a house that needs maintenance like any other. Who does what is purely circumstantial and has been mostly fair across the board. I feel sorry for people who need to sit down and talk about such menial bullshit. If you do, then one or both of you simply isn't mature, reasonable or responsible enough to share a household with someone else.
