Does it Really Matter?

Robbie and I don't see much of each other during the week, but even in the short time that we are together we end up talking about trains! Yesterday evening there was an advert on TV, I think it was for insurance, but it had a brief shot of a train and then you saw the people inside the train discussing insurance or whatever it was. I made the foolish mistake of asking Robbie about the livery of the train, he confidently told me what it was and then he got one of his books out to show me. I told him he was wrong and we got into a pantomime argument of "yes it was, no it wasn't" with neither of us willing to give in. Robbie decided to prove that he was right by rewinding the TV to check - he was wrong!! Then he spent an age debating (with himself) whether or not the interior shots were from the same train, he decided that he didn't think they were, I couldn't care less, I had lost the will to live by then!
