Reggie: We're going to a party tonight. Do you want to join us?
Ophelia: No, I can't. I have to finish my homework.
Reggie: Do you have a lot of homework?
Ophelia: Yes. I have a math test tomorrow too.
Reggie: That's too bad. It's supposed to be a big party.
Ophelia: I wish I could go, but I'm so behind in my classes.
Reggie: Why are you so behind?
Ophelia: I was sick for a few days and missed several classes.
Reggie: Do you need help studying?
Ophelia: No. I just need to focus on my school work.
