Well, I layered up in the winter months as, no doubt, did many of us on GN.
Born during the war living through the winter of 1947, when despite the cold fuel was limited. Growing up in houses when heating consisted of a boiler that heated the water in the kitchen and a fire in one living room, my usual layers in winter were vest, liberty bodice, sweater, with below the waist, thick large knickers, long woolly socks and a pleated woollen skirt. When I left the house, all I added was a coat and gloves. At night I had a warm wincyette long sleeved night dress, a warm dressing gown and ahot water bottle to warm the bed with.
I think children faced with the choice of wearing an additional layer or two or freezing will make the sensible decision.
Bear in mind that we have had a long and exceptional hot and dry summer, something experienced all over the world directly due to our consumption of hydro carbon fuels, so in fact, if the price of gas and electricity means that we consume less, it can only be good for the world. Yes I am aware of the terrible increased prices will have on most families, I am just pointing out an unforeseen gain that will benefit the planet.
