There are three professors at the railway station. They were deep in conversation. The train had just arrived, but they didn’t notice to it. Then the guard shouts, “Take your seats please!” The professors heard the guard and rushed for a train. Two of them got on the train after it closed and moved. The third one was left behind. It was Professor Egghead. He looked worrying. One of the professor’s student was at the station. He tried his best to comforting the professor. “It wasn’t really badly, sir,” said the student. “Two out of three caught the train. That is quite good, you know.” “I know,” the professor said, “But it was mine train. My friends only came to say goodbye.”
