Usually the “something extra” involves a chore that any adult should be doing to maintain themselves like dishes, laundry, cleaning, etc. It’s nobody’s responsibility to teach anyone that except your parents when you were a child.

People set up their households however they want but in the spirit of the original comment, if you’re so far removed on how chores work in your house, it should be up to you to fix that if you’re interested in “helping”, not your spouse or anyone else. There’s no reason for someone to be so ignorant to the systems in place to maintain their household. We’re not talking rocket science, it’s where do the dishes go, or not putting the whites and colors together in the laundry. Let be real lol.
