[A knock at the door.] Come in, please.
Hello, Kate. Where's Jane? I want her to type this letter for me.
I'm afraid she can't, Tom. She isn't working today.
Oh, why? Is she ill?
No. She's studying for an exam.
An exam. Is she going to school?
Yes, she is. She's learning Japanese in night school.
I see. Are you going to night school, too?
No, I'm not, not this year. But I'm thinking about taking a course next year.
That's a good idea. Is it expensive?
