I have an appointment for half past one.
What can I help you with?
Well, I have a problem with my class schedule.
What is it?
It seems that I've been given two classes scheduled at the same time.
I can understand the problem with that.
Is there any way that you can fix my schedule?
No problem, do you want those classes still?
Yes, I do.
Let me see if I can find one of these classes on another day.
