Could you give me a context in which it is used.
NOT A TEACHER
Here is perhaps one possible context:
Tom: The party is scheduled for next week. Have you mailed all the invitations?
Mona: Yes, I have. I took them to the post office this morning. Here is the list of the 50 invitees.
Mona: What's the problem?
Tom: I don't see Mary's name on the list.
Mona: I don't like her. Should I have invited Mary?
Tom: Of course, you should have. People say that she will be our new manager.
