"How Did They Know?"
This reminds me of something that happened to me nearly 50 years ago. One day, when I was a 14 year old grammar school pupil, I cashed in my savings stamps, those with the head of Princess Anne on, 6d each, in order to buy two new ball point pens for school. Having bought the pens I had the munificent sum of 3s left over. Outside the large department store where I purchased the pens a blind man used to stand playing the accordion, soliciting donations. Chuffed to bits with my new pens and feeling in a most magnanimous mood I put 6d in his collecting box. He turned to me and said, "Thanks, bonny lad." I was half way further up the street before it hit me.
