M:Hey, Jane, can you go to the movies on Saturday?
W:Well, I'd love to but I don't know. What time is it?
M:How about seven o'clock after dinner?
W:I'd love to, but I'm sorry I can't. I have to study for my math test.
M:Well, you can study in the morning and afternoon and then go to the movie.
W:Yes, but I have to help my mother to clean the house because my aunt is coming to visit us.
M:That's too bad. Maybe another time.
W:Sure, Dave. Thanks for asking.
