Answer:
this statement refers to house wives/husbands.
Explanation:
the spouses that stays at home, regardless the gender, they are the ones who works hard, for me people who do not experience it doesn't know how hard to multitask inside our houses. Cleaning the floor while cooking and doing the laundry is already hard, what more if you have to take care of kids and when the spouse who works gets home, you also have to take care of them.
