M: Do you know what happened to me today? I was so embarrassed.
W: What?
M: Well, I had to stay up late last night because 1 had to finish the homework Professor Brown had assigned to us. I got up late this morning. When I opened my eyes, it was 7,45.
W: Oh, it’s terrible, the class begins in 15 minutes!
M: Yes, so I put on my clothes and rushed out my dormitory. I had no time to have my breakfast in the dinning hall, so I ran into a store, grabbed a piece of bread and left there as quickly as possible, when I got to the classroom, it’s about to get started.
W: Well, is there any thing wrong?
M: Absolutely, when I just left the store, I noticed that somebody followed out, but I was in such a hurry that I didn’t stop. When the class was over and I was about to leave, my supervisor, Mr. Black, showed up with a middle-aged man. Mr. Black said the man told him that I had stolen some bread in his store, he traced me out by the book I left in the store with my name on it.
W: How can I believe that?
M: So did I ! But suddenly I realized what had happened,  I forgot to pay for the bread. So I made the explanation to him and apologized for that.
W: Yeah, It really embarrassing.
