I had a funny experience when I had to catch a train for a meeting. I have never been traveled on train before. I took an early morning train to where I had to meet my professor. At the station I read a sign “For Oakliegh Station, Please Board Four Rear Cars Only”. Then I boarded the rain but did not notice the position of my carriage. When I got to my destination, the train door was locked. It could not be opened. I panicked and forced it to open. I thought there must be something wrong. There was no platform. So I jumped off the train lines and had to cross the railway lines to reach the platform. A fast train came from the other direction. I was so shocked. After I met my professor, I told him the story. He explained, if the sign says please board four rear cars only, it means that the train only has a short platform. I realized that I was so stupid but I was so lucky that morning. Why did the writer panic on the train when he got to his destination?
