I have no personal animus against Andy Murray, and I dare say it is irritating not to win a tennis match, but precisely when did we turn into a nation of snivelling losers? At what point in the history of the last hundred years did the stiff upper lip start to quiver; Did it stop being shameful for a grown man to burst into tears just because he came second in a game? Did it become possible for a serial runner-up to become 'champion of our hearts' not with a bang, but a whimper?
