My Day

My day starts early in the morning. I wake up at half past six in the morning and lay in bed for twenty minutes. So, I get up at ten to seven. I make my bed first. Then I go to the bathroom to have a shower and brush my teeth.

Then I dry my hair and comb it. It takes me 20 minutes. Then I get dressed and go to the kitchen at twenty to eight. I cook my breakfast myself. I usually have scrambled eggs, a cup of tea, a toast with butter and jam. I leave home at five past eight. My classes start at half past eight, and I live a block away from the school, so I always walk. It’s a fifteen-minute walk. I usually come to school at twenty past eight.

I usually have five classes a day. I like to have lunch at school with my friends. Our lunch is usually at twenty-five past eleven. Then we have some more classes. Our last lesson finishes at five to three.

At home I do my homework first of all. It doesn’t take me long and I am usually free at quarter to five. I do some housework, play video games and go for a walk. At half past six my family has dinner. We eat and talk about our day.

In the evening I like to read for half an hour. At ten to ten I go to the bathroom, wash my face, and brush my teeth. I go to bed at ten o’clock.
