A: It's already past ten, but Mr. Bailey hasn't came back yet.
B: He's really late, isn't he?
C: Oh, yes. He called a little while ago and said that he would be spending the night with relatives
and would not be coming back to dormitory.
A: Is that so? We are having an examination tomorrow. Do you suppose he'll be all right?
C: Don't worry about him. He has been keeping up with his work all along.
A: That's right. I usually fool around, so I have to study terribly hard before exams.
B: I have been reading the same book over and over again, but I just can't seem to remember
what's in it.
C: Well, let's keep at it a little longer.
There's an exam tomorrow, so everybody is still up studying very hard even though it's already past ten o'clock. But Baily has gone to stay with relatives. He doesn't have to do any special studying up, because he studies hard all the time.
