Doing household chores is a necessary part of our life. People are happy when the home is always bright and clean. Day after I do my household chores. I sweep the floor, tidy my room, clean the shoes, dust the furniture, make food myself and do every kind of work. I do most of the washing up, tidy my room and make my bed. Cleaning the room is probably the best one, and the worst I think is cleaning the bath, because it kills your back. My father and I try to help my mother to do the chores. Everyone in the family is responsible for cleaning and repairing things when they have free time.

As for me, I have my own household chores, as well as, other members of my family. Cooking is the main responsibility of my mum and I sometimes help her with that. My own chores include washing the dishes, cleaning the dust and vacuum cleaning. My father is responsible for repairing some devices and objects in our flat. There is one thing that all the members of my family do together. It’s shopping for food and for clothes. I can’t say that these chores are difficult or take a lot of my time. I know that only several years ago women spent much more time on house work, when they didn’t have such household appliances as microwave, washing machine, vacuum cleaner, blender and others. In my opinion, having certain responsibilities is very important. It helps to understand and respect other people’s work, and also to overcome laziness.

Why is doing household chores a necessary part of our life?

What chores does the speaker do?
What chore is the worst one?
