(Mr Grey is waiting at the railway station for a train)
Mr Grey: Hey! This train's late! I've been waiting here for ages.
Porter: Which train, sir?
Mr Grey: The 8.18 to Baker Street.
Porter: The 8.18? I'm afraid you've made a mistake, sir.
Mr G r ey: A mistake? My timetable says: Baker Street train — 8.18.
Porter: Oh no, sir. The Baker Street train leaves at 8.08.
Mr Grey: At 8.08?
Porter: You see, sir, they changed the timetable at the end of April. It's the first of May today.
Mr Grey: Changed it? May I see the new timetable? What does it say?
P î r t e r: It says: Baker Street train — 8.08.
Mr Grey: Hh! So the train isn't late. I'm late.
