#Person1#: Come to my office, Billy. Look at your messy hair. This is the third time you have been late for class within this week. And every time you went in, you disturbed the teacher's class.
#Person2#: Sorry, Miss. I didn't mean to do that, but it was my alarm clock that didn't wake me up.
#Person1#: That is not a proper excuse. You could set it ahead of the exact time so that you could have got up earlier and not have been late.
#Person2#: I did that, but it seemed useless when I found the batteries had run out after I woke up this morning. I rushed to school and luckily, my neighbour Mr. Green gave me a hand and took me to school with his car.
#Person1#: So you could have made it. But you were still late for class.
#Person2#: The thing is, when I got off, I found I had left my bag in his car. And it was too late to get it back when I realized that. I went straight to the nearest shop and gave him a call. I waited for five minutes before Mr. Green drove back.
#Person1#: Finally, he gave you your bag and you came to the classroom and you were already 15 minutes late for class at that time. Is that all?
#Person2#: Miss, you seem to know the entire story. May I go back to class now? Otherwise I will be late for the following class.
Billy explains why he was late for class to #Person1#. His alarm clock didn't work this morning. His neighbor gave him a ride but he left his bag in the car, so he went to the nearest shop to call his neighbor and waited for the bag.
