     We have all experienced days when everything goes wrong. A day may begin well enough, but

suddenly everything seems to get out of control. It seems as if a single unimportant event may cause a

number of things to happen. Let us suppose that you are preparing a meal and keeping an eye on the

baby at the same time. The telephone rings and this means your troubles are beginning. While you are on

the phone, the baby pulls the table-cloth off the table, destroying your half prepared meal. You hang up

hurriedly and attend to your baby. Meanwhile, the meal gets burnt. As if this were not enough to bring

you to tears, your husband arrives, unexpectedly bringing three guests to dinner.

     Things can go wrong on a number of people on the road. During the rush hour one evening two cars

hit each other and both drivers began to argue. The woman driver behind the two cars happened to be a

learner. She suddenly go into a panic (恐慌) and stopped her car. This made the driver following her

stop suddenly. His wife was sitting beside him holding a large cake. As she was thrown forward, the

cake went right through the window and landed on the road. Seeing a cake flying through the air, a

truck-driver had to stop his truck all of a sudden. The truck was carrying empty beer bottles and

hundreds of them slid off the back of the truck on to the road. This led to yet another angry argument.

Meanwhile, the traffic piled up behind. It took the police nearly an hour to get the traffic on the move

again. In the meanwhile, the truck-driver had to sweep up hundreds of broken bottles. Only two dogs

were enjoying themselves from the accident, for they were happily having what was left of the cake. It

was just one of those days!
