Dialogue:
Aisha: Hello, Sam. Could you possibly lend me your lecture notes from yesterday?
Sam: Of course, I can lend you mine. However, I might have left them at home this morning.
Ayesha: That's fine. I'd rather have them tomorrow than never.
Sam: What are you going to use them for? I'm guessing it's for the quiz the next class.
Aisha: You might be correct, but let me explain. I'm studying for the quiz, and I think I misplaced my notes.
Sam: Okay, then. Explain.
Aisha: I've been battling with several ideas. I'm having trouble understanding how to use modal verbs. Could you perhaps explain this to me before the quiz?
