Trains (and mobile phones)

As I spend some 2-3 days each week in London, I am bowling up and down on the Chiltern Railway between Solihull and London Marylebone a fair bit. The trains on this route are reasonably new and the journey is just what a train ride should be. It is comfortable (I can almost always get the seat I want), quick, and passably relaxing. The only variable is my fellow passengers. I usually sit in the "Quiet Coach" where passengers are requested not to use a mobile phone. It is amazing how many people are so wrapped up in their own little world that they don't see these. As a result I usually let them finish one conversation before inviting them to move to another carriage. Last week there was the most graceless man who shouted at people even before they had started to use their phone. Please don't let me become like that.
