An old porter had worked for the railway for a very long time. One morning he was standing in one of the big railway stations and waiting for travellers to ask him to help them with their luggage, when he saw a small man running towards the trains with a big bag in his hand.
The porter watched the man for a few seconds, and then the man saw the porter. At once the small man ran up to the porter and said,“Can I catch the 10:35 train to London, porter?”He was breathing very fast, and he looked worried.
The old porter looked at him for a moment and then said with a smile,“Well, sir. I'd like to help you, but I can't answer your question because I don't know how fast you can run along rails.”“You see,”he explained,“The 10:35 train to London left five minutes ago.”
