My assumption was the joke was that OP's mom does their laundry for them as if is OP was a child, not that women are constrained to doing laundry. It's not like I didn't clock the joke. The kernel of truth was the idea that doing those 3 things might be a pain to do, and even my partner complained about having to be careful with certain clothing when I taught her how to do the laundry (which I still primarily do), but it's good for people to have these skills, regardless of gender. On the flip side, she stopped complaining when she realized how much longer her clothing lasts now.

Also, my parents divided chores up, and my mom was in charge of the laundry while my dad did the cooking growing up because they each preferred doing those chores. Had nothing to do with gender, but maybe that's why I didn't immediately consider the assumption that somebody's mother does their laundry as sexist. Sometimes, it's just like that.

On the topic of you making wild assumptions about another's thought process (unless you're a mind reader, and I missed that), I was carrying on to say with my comment that OP should do all that. Not their mother.
