I’m really lucky because I (1) mustn’t / don’t have to wait to talk to my best friend at school. My best friend is my older sister, Karen, and we share a bedroom. However, we do have some rules. For example, there are borrowing rules. I (2) mustn’t / must borrow her clothes and she (3) has to / doesn’t have to ask me when she wants to use my mp3 player. We also (4) have to / must have other rules for our bedroom. We both (5) mustn’t / must keep our stuff tidy. We have one more rule. Because Karen’s older than me, she (6) doesn’t have to / mustn’t go to bed when I do, but when she comes to bed, she (7) must / mustn’t

wake me up if I’m asleep! Luckily she’s really kind, so she never does. I (8) must / don’t have to be more like her!
