My late father, no stranger himself to the odd eccentricity, used to love telling the story of the late Sir William Eden.
100 years ago, this baronet father of the future Prime Minister Sir Anthony Eden, was in the habit of tapping the barometer in his hall each morning. Once, when it was pouring with rain but the barometer forecast sunshine, he hurled the instrument outside yelling: "Go on, you damned fool, go and see for yourself!".
Sadly, I found myself this morning following in this fine tradition by demonstrating the outside rain to my iPhone Rain App.
