I began my preaching yesterday evening with an anecdote from childhood. It is from the days of cigarettes and fireplaces. It is of my nana or grandmother (my dad's mam) leaning over the open coal fire at home and burning the edge of the white tissue paper on the back of the foil from a packet of her cigarettes (Gold Flake or Kensitas she used to smoke – lots of people smoked in those days). She was then able to peel the white paper from the foil and add it to her collection of silver paper.
Lots of people collected silver paper in those days, in the sixties. My other nana who didn't smoke was collecting it too. The silver foil was sold to companies who would use it tin the steel making process. The money they paid for it was used by charities seeking to help the blind.
There was quite a high awareness of the needs of the blind then. My parents and grandparents were especially concerned about toxacariasis, which can be caught from dog faeces, if the dog has ring worm. They always seemed to be reading about cases where children had become blind by this means.
