HOUSEHOLDING CHORES
Doing a work about the house is often called 'doing chores'. Doing chores helps a family to 'hold their house' or in other words 'to household'. Usually a member of a family has a householding duty. It means he or she has a part of chores to do. There are the things like feeding a pet, cleaning the carpets or doing shopping...
On weekends my friend's family members are seldom all at home at the same time, so they write notes to each other. They help them to remember things to do.
My mother is the busiest person in the householding chores. And I must admit1 my elder sister is the greatest helping hand for her.
Every morning mother cooks breakfast. She fries some eggs in the frying pan. My sister sometimes boils sausages in a small pot. When the eggs are ready, mum serves them to us with nicely-decorated salad and boiled sausages. While my mother is doing that, my sister is cutting some bread and taking out the tea-pot, cups and plates.
When the water in the kettle boils, my sister puts some tea into the teapot, pours some of the boiling water into the pot and the tea is ready.
Sometimes my mum prefers coffee to tea. Then my father prepares it. He is good at making coffee. I never drink coffee. I prefer tea. My sister sometimes drinks coffee with milk or cream. After breakfast I go to my school and my father goes to his office. My sister washes up the dishes and dries them with the dishwasher machine. My mum cleans the table and takes off the clothes.
My sister puts clean cups and dishes onto the cupboard and goes to her job.
And what about mum? She stays at home and does lots of things about the house. There is always something to do, a woman's work is never done...
