Listen to a conversation between a student and her geology professor.
Mary, I'm so glad I ran into you.
Oh hello, Professor Jensen.
Listen, I know it's a short notice ...and maybe you've already made plans for spring break ...but ...one of my students just dropped out of the field trip to the Smithson River Caves.
You're next on the waiting list, so now there's room for you to come along.
I didn't think there was a chance ...and ...well, it's a three-day trip, right?
I agreed to spend next week helping Professor Clark set up the new museum exhibition.
I think she's really counting on me.
Yeah, three days.
But you know ...if you'd rather come on the field trip, why not speak with her and see if she has anyone to replace you?
Yeah, I'd hate to miss out on the caves.
I'll definitely ask Professor Clark if there's someone else who could help her.
You know...we don’t leave until Wednesday.
If you still have to help out, any chance you could get the museum-setup done before then?
Oh yeah ...not until Wednesday ...so then yeah ...maybe that's possible too.
