Listen to a conversation between two students.
Male Student: Hey. Lin. What’s up?
Female Student: Oh. Just getting ready for my grandmother to come to town. She is flying in tomorrow to visit me for a few days at school.
Male Student: Oh. Yeah. Is she going to stay at your apartment?
Female Student: Yeah. It would be good. We can spend some time together and I can show her around campus and stuff.
Male Student: Sounds nice.
Female Student: Yeah. I am looking forward to it. But I am not sure what to do about picking her up from the airport.
Male Student: What do you mean?
Female Student: Well, her flight gets in tomorrow. But the problem is, my biology professor scheduled a special review session…uh…for an upcoming biology exam at the same time I am supposed to pick her up. I didn’t know there’d be this conflict.
Male Student: Oh. Well, how important is the review session? Do you think you can miss it to pick your grandmother up?
Female Student: It’s optional. But this professor’s review sessions are usually really helpful, he does a good job going over what’s going to be on the exam. So it would be good to go, but… maybe I’ll have to miss it.
Male Student: Is there something else you could do?
Female Student: Yeah. Actually I spoke with my friend Mary and she offered to pick my grandma up from the airport.
Male Student: Great. Why don’t you do that then?
Female Student: Maybe. But Mary doesn’t even know my grandmother. And I don’t know how grandma would feel about being picked up by a stranger. She’d probably be more comfortable being picked up by me.
Male Student: Oh. Well…
