I have to learn English. They have to know this. We have to do something for him. Our friends have to be there. My parents have to stay there. You have to help him. You needn't do that. They needn't go to school. Marry and Tom needn't stay here. We needn't speak with them. I and you needn't be sad. The girls needn't read this book. You don't have to write this. We don't have to sleep right now. They don't have to know everything. Our friends don't have to stay with us. You don't have to be nice with her. Horses don't have to run away.
