Prof: Why were you absent from class yesterday,Paul?
    Paul: My mother was sick. I had to take care of her.
    Prof: That was very kind of you,Paul.
    Paul: Oh,no,sir. Every boy should take care of his mother.
    Prof: The day before yesterday you said your father was sick.
    Paul: I did?
    Prof: Yes,you said you had to take care of him,too.
    Paul: Oh... Yes. That's right. He was sick,too.
    Prof: How are your father and your mother now,Paul?
    Paul: They're fine,sir.
    Prof: That's good. Tomorrow we're going to have an exam.
    Paul: Ooooh!
    Prof: What's the matter,Paul?
    Paul: It's my stomach. I think I'm going to be sick tomorrow.
