At school i do three hours of sport a week. Ive always hated sport . When i can,i miss the lessons. This term ive pretended that ive hurt my leg so i dont need to do any sports at school. I even go to the doctor every week to do special exercises for my leg . The problem is that i cant pretend that ive got a problem with my leg all year. i really dont know what to do, im in such a mess . i really feel so bad about this . what should i do? в чем его причина? напишите по английски, от третьего лица
