😒😑 why do wives always get the shit end of the stick

I had my son by myself Saturday and Sunday while my husband worked. Sunday, I spent the whole day cleaning the house, doing laundry, grocery shopping, and cooking dinner all with my son strapped to me. My husband came home from worked to a meal in the fridge, clean clothes and a clean house. Then during the night I was up for 2 hours with the baby. Then I got up and went to work. I just came home from work to nothing but a trashed house and my husband immediately going to lay down cause he's sooo tired. Why the fuck are things this way
