Read the text and answer the question.Hello! My name is Emma and I'm 12 years old. I have a big family - my dad, my mum, my two brothers, my two sisters, my grandma, my grandpa, my uncle, my aunt and my cousin.My house is never tidy! My brothers are very lazy so they don't tidy their room. My sisters are OK. They help a bit with the housework. My grandma always cooks lunch and dinner. My grandpa doesn't do anything. He's retired. My uncle is very helpful. He often does the washing-up. My aunt sometimes does the cooking. My cousin is only three so he can't do anything!At the weekends, my mum often tidies up the house. She sweeps the floor, waters the plants and does the laundry. My dad doesn't do the ironing. He isn't very good at it! He usually fixes things. Last weekend, he fixed the TV. This weekend, he's going to fix the computer.I love cooking. I often cook dinner for my family. On Sundays, I usually cook roast chicken. First, I peel the potatoes. Then I slice them. After that, I boil them. I put some oil on the chicken and then I put it in the oven. Finally, I mash the potatoes and mix the gravy. Yum!What household chores does Emma's mum do on weekends?
