You drive to the station. On the way, you drop your daughter at school. Her first lesson today is English. Her teacher is 72 year old Mrs MacDuff. You park your car and buy your weekly ticket from Alan, who has been at this station for 5 years. Alan is 68. At the next station, your good friend Margo gets on. Margo works at your bank. She is 74. But she tells people she’s 69. Before going up to your office, you buy a coffee. You’re served by Ralph as usual. Ralph has just turned 80. You’re about to get in the lift when a young punk barges past, iPod blaring, and punches the Door Close button impatiently. “Kids today have no breeding,” you think. “Can’t be a day over 50 and he thinks he owns the world.”
