All of us have a lot of duties. Doing household chores is a necessary part of our life. I usually make my home clean at Sundays, because it's a day, when I don't go to school/college. I have 3 rooms ("у меня три комнаты" - можете поменять на 4,5...) and first of all I clean my own room. There is a wardrobe, a bed, a bookcase, a desk with computer on it and pot plants on the windowsill. So I sweep the floor, fold cloths, dusting and water plants. I don't always clean all rooms, but sometimes I have to do this. But I always wash dishes after eating and my little sister/brother helps me with it. ("Но я всегда мою посуду после еды и моя младшая сестра/брат помогает мне с этим", можете написать "старший-big/older"). If I have time my mom asks me go the store and buy some products. We cook together quite often. After holidays my parents get tired and I clean up almost all flat and it's a nice present for my parents to tide the house! We must to do our household chores, because if we hadn't done it our flat would look like a trash. It is necessary to help parents and hold your house clean.
