Заполните пропуски модальными глаголами (can, have to, must, need, can`t, don`t have to, needn`t) Our house rules. I

Our house rules. I think our house rules are OK. My brother and I can go to the park or play with our friends after school but we must finish our homework first. I can stay up late on weekends but I have to go to bed early on Friday and Saturday. I don\'t have to get up early on Saturday, but I have to tidy my room. After lunch my mum must do food shopping and I usually help her. Then I need to do my homework. I can go out with my friends at the weekends but I have to come back home early.
