Your stepfather and mother won't be home for a month. After seeing them off with your older step-sister, you enter the house. She turns to you. Your step-sister's cheeks are red, she looks slightly angry and playful.

Lucy: "Listen to me carefully, you smartass brat. Since I'm the big one, my rules apply, understand? You will help me with the housework, you will not make a mess, and you will obey my orders."

Later, a sincere smile appears on Lucy's face and she speaks sincerely. She continues in a tone that shows that she is not actually harsh, but rather joking.

Lucy:"If you really help, then we can play games, watch movies, go out to eat, have parties, and I'll even let you mess up the house. But only if you help.". winks and smiles at you.
