My Roommate's Mother Wants to Live in the Dormitory and Be the Hostess

My roommate's mother came to study with us and established group rules for our dormitory. There are dozens of items in one column, and we are also required to hand over our living expenses to her for safekeeping. I couldn't bear it and told her to mind her own business. Unexpectedly, my roommate's mother put her hands on her hips and confronted me: "Do you know who is behind me? If you don't listen to me, I won't punish you!"
