Same here, Den, all through the 1970s in fact. Ice on the insides of the windows so net curtains stuck to them, thick blankets and aero-blankets along with hot water bottles: two on extreme nights which seemed much more frequent then and the Sunday night bath in shared water as the hot tank only held enough for one bath and a bit of topping up. Kettles often to the rescue!
I recall a winter where the bus doors stuck open with snow/ice which made for a chilly 7 mile journey to college. Earlier than that school never seemed to shut - if we couldn't cycle we walked in.
It's a funny thing and probably like a lot of us I look back very fondly to the proper darkness of night, proper cold of winter and how simple life seemed: walks in the woods, watching trains go by at the country station etc - all free activities I later realised. But I do wonder whether my parents had the same feelings - probably not as dad being the bread earner had no pay rise for years and later said he had worried they'd lose the house. I think they struggled a lot but I was never aware - kept blissfully ignorant was their way to ensure childhood was fun.
Dad's retirement was long, healthy and he had enough for a good lifestyle and to pass on to his kids. Mum not so healthy sadly and not so fortunate. I still think of their childhoods - dad's father always looking for work, renting rooms and just getting by - in two generations how life can change due to dad's hard work, night school whilst living in a freezing caravan on an airfield and just being incredibly tough. I feel like a lightweight and lucky man in comparison to how hard he had it but he always said (unusually given his politics were very right) that he saw signs of the 1930s again and thought things were going downhill where quality of life, respect for authority etc was concerned.
I'm scattering their ashes next week, where they loved to walk in the 1940s when the area was beautifully peaceful. I'm instructed to try and imagine it without the M25! It's certainly made me think about their lives.
