Because you live there too. You are also using water + gas + light. Unless you are in high school or elderly or a baby you shouldn’t pay a bill. But if you are able bodied and get 2 checks if you working biweekly or 4 checks if you working weekly you should pay a bill.
Call me brain washed idc. But you working and you still live at your parents house yes I do think you should pay a bill there or rent there. Because yes you do use those items.
when people get irritated at calling things like fête de la music “fete” and calling carnival “carni” i just keep quiet because shortening words is my favourite british thing to do sorry
