I want to tell you about my day. I get up at 7 am and go to the bathroom. I wash my face, brush my teeth and comb my hair. Then I go to the kitchen and have breakfast there. I usually have porridge and a sandwich with tea for breakfast. After that I walk with my dog. At 8 o’clock I start doing my homework.
I usually have six lessons in distance learning. After training, I have lunch. I do my homework after dinner. For the rest of the day I help my mother around the house and do my own things. In the evening I watch TV and go to bed at 10 o’clock.
