This morning I got up to absolute torrential rain. The patio was flooded and water was pouring down the road. This was at half past six. By the time my Carer came at half past seven it was just 'ordinary' rain and by half past ten, when I had more or less finished most of the Mind Games in The Times, the sun came out and the sky was blue. I decided to take the bull by the horns and go for my walk - it was glorious, a real Summer's Day. On the way back there were a few ominous clouds and I debated which way to return. It suddenly struck me that the paths involved formed a more or less perfect right angled triangle so - obviously - I had to apply the Pythagoras theorem (the square on the hypotenuse is equal to the sum of the square on the other two sides). Miss Bayliss, my maths teacher, would have been proud of me. (we always called her Bertha Martha because her sister, Annis, always called Miss Annis was our house mistress). If she is looking down on me I would like her to know that in all my eighty eight years that is the first time I have found it useful.
As it happens unnecessary though - now, two hours later, it is still a glorious Summer's Day.
