My week routine is very interesting thing to talk about it. Monday - is the start of a week in Russia, on this day I have 6 lessons at my school. After school I go to the volleyball section. I like to do sports and I spend my time with a big pleasure giving a conversation with my friends and improving my sport skills. After I go home and do my homework. Then I have dinner with my parents and go to sleep. On Tuesday I also have 6 lessons, but this day is much harder, because I have physics, maths and chemistry on one day. After school I feel tired and go home to take some rest and to have a meal. Usually I read a book or talk with my friends on the Internet. On Wednesday after school I go to visit my granny. We drink tea and granny tells me various stories. She also can help me with my school task. (And she bakes a great cakes! :)) At home I finish my homework, help my mum with dinner, and go to bed. That's 3 days of my week.
