My school was closed for a few days in 1963. When we went back my Mum had to walk over a mile each way through the snow (twice) to get me there and collect me. Girls had a special dispensation to wear trousers which were usually forbidden. The outdoor toilets were frozen solid but we had to use them anyway. I don't think we were tougher then just more miserable I wouldn't have wished it on my child and I don't wish it on my grandchildren. Besides which teachers probably lived closer and could walk in and I doubt if any had their own small children to take to childminders etc. first as women usually left when they married or, at least, when they had their first child.
