Need some help with my homework ! Hi everyone, my english teacher asked as to prepare a dialogue between the headmistress, a teacher and an unruly student. the teacher will talk to headmistress about punishing this student, the student will try to ask for forgiveness... unfortunately I'm still facing some problems especialy with speaking formally. I want to know how can both the pupil and the teacher adress the headmistress (by saying hi mrs the mistress, hi mrs or s,th else ). And if it's possible to give me some ideas. Thanks.
