I have very clear memories of that winter. Brilliant watching that film, by Ridley Scott, too!
I was the first at my junior school to wear long trousers, and, as jota180 says, teachers used to turn up in those days, you have to remember that most towns were much smaller, villages had their own schools, the town schools had very much smaller catchment areas, and the teachers lived locally, because few people had cars. Chippenham, which has a current population of around 50,000, was only 19,000 back then. You could buy a little book in WHSmith which had all the streets in town listed, with the name of everyone in each street!
I used to wake up each morning, with frost patterns on my bedroom windows, and my bedroom walls sparkling with frost!
Now, if someone hasn’t got a room temperature of 75 degrees, they’re hard done-by!
