#Person1#: Hello,this is Susan speaking. Is Mr. Brown in, please?
#Person2#: Yes, speaking.
#Person1#: Hi,Mr. Brown. Your son Ted missed the school trip this morning. Do you know why?
#Person2#: Yes. He got up a bit late this morning. He missed the school bus.
#Person1#: Why did he get up late? Didn't he have a clock?
#Person2#: The clock didn't work this morning. I worked overtime till midnight at home last night, so I got up late,too. It was already nine o'clock when I woke him up.
#Person1#: Well,why did he wake up at such a late hour? Did he go to bed late last night?
#Person2#: Yes. He didn't go to bed until 11:00 pm.
#Person1#: Why didn't you ask him to go to bed early?
#Person2#: He's a 'night owl'. He can't fall asleep before 11:00 pm.
#Person1#: You should really change his sleeping habits. Otherwise it will happen again.
#Person2#: I will. Thank you for calling, Susan.
