Dear friend,

School classes always make me tired, so I often go for a walk with my friends after it. We can go to the park, to the cinema, to the stores just for a window-shopping. Sometimes we're going to the computer club to play computer games. My friends are fond of it. I'm fond of music, so after school I also have additional classes for playing guitar. It also helps me to relax. But sometimes when I have a bad mood after classes I go home and listen to my favourite music. Music helps me to relax and to forget about my bad mood. I also like to watch TV, especially different TV shows. Also I clean my room once a week. But after my rehab I have to do my homework. It's easier, when you've just had a rest and your mood is good. So, that's some part of my leasure time after the school classes. 
I hope to receive your letter soon. Have a nice day.
                                                                                    Sincerely, your (имя)
