I don't live with my mum anymore. When I did she did most of the housework, but I wouldn't have her clean my room at all (I kept it tidy myself so it never needed cleaning) and I'd make my own meals; which only left the laundry and vacuuming to do, so she wasn't really overburdened. She would drive me to school though.
Now, when I visit my mum, she cooks for me. But I usually only stay for about 2 days so there's not enough time for me to make a huge pile of chores to clean up after me, lol.
My brother orders my mum around as if she's a servant and it really annoys me, he's never polite, always yelling orders and she just does everything he tells her. It's ridiculous and no matter how many times I rant at him, he doesn't change. My mum somehow doesn't even have a problem with it though, so no harm done I guess.
