When I was home on leave (I joined the military at 17), I'd do chores if I was actually living with my parents for a week or two... but now that I'm out... I most certainly don't. I don't live with them.
My sister and brother both lived at home while in college, and my mum drove them NUTS. They had work schedules, school schedules, study schedules, and social lives... and our mum kept "assigning" them chores to do (like unload the dishwasher) that did NOT work with their schedules. She would also get livid if she didn't know by 4pm (or earlier depending on her mood) if they were going to be home for dinner.
I finally sat her down at coffee one day when she was complaining about them and had a hash out. I was on my own at 17, and had to do everything for myself. Yet here my sibs were, years older than I was, being treated like highschoolers, like our younger siblings. My parents had OFFERED for them to live at home while going to school (to save money), but they were making the deal very one sided. They had none of the privileges of being an adult (setting their own schedules, being single and not needing to be responsible to others, allowed to take advantage of last minute plans or deciding to pull an all nighter, etc.), and ALL of the downsides of being a child. If my parents wanted them to act like adults, they needed to TREAT them like adults. They wouldn't ask a friend who was over for dinner to do their other children's laundry, or yell at a friend for being late or canceling, but because my bro and sis were their kids they felt free to "assign" and to guilt trip, and yell.
From then on, my mum let them go, and quit treating them like children. She quit asking them to do chores, but also quit doing anything for them (like laundry, cooking, etc.). And she was *amazingly* strong to do it in a non-snarky way. (She actually apologized for treating them like kids.) When she found their clothes in the wash, she put them in a pile and didn't touch them. When they came home around dinner time, they were more than welcome to grab a sammie, or any food that was left over... but she didn't go to special effort for them unless it was a prearranged dinner date. When my sister *did* inevitable complain (my brother was just relieved she'd quit micromanaging his life), my mum laughed and said that my sis was an adult. If she wanted help, then she needed to ask AND reciprocate (aka if she wanted dinner made for her, then to CALL and set it up, and then to help with either cooking or dishes, but not to dine and dash. And if she dined and dashed, expect not to eat with them for some time). My sister has this food issue, so she started eating most meals at my parents (and helping clean up afterwards). When she DID also eventually dine and dash, my mum cut her off for the next couple weeks.
The whole thing relieved SO much tension around their house.
