Dunnit!

Yesterday’s earthquake stories from the north of Japan’s main island reminded me that I’ve actually been in one myself.
    Not an R7.6, I hasten to add. I was in a friend’s kitchen years ago and he was about to put the kettle on for a brew of tea when we heard a rattling noise.
    It was the empty kettle bouncing about on the hob. Just for about ten or twelve seconds. My friend reckoned the Manchester area was getting small ones like this every few days.
