Do I really have to eat my partner's cooking? I'm not going to.
Why wouldn't you want to eat your partner's cooking?
They took too long to cook, had too many burn marks on the chop, tasted like shit
You're mean to criticize your partner's cooking. I understand they can't cook very good food but at least they're doing efforts for you. You should appreciate them.
I can say whatever I want and cook until I want, you stay out of it.
You should appreciate your partner's efforts to cook for you. With time and practice your partner will get better. However, your poor attitude will make the relationship worse.
