We had a real tree. (My mother wouldn't permit anything else. She'd been 'in service' for a Harley Street doctor and everything in our house always had to be done "like it was in the big house"). My father was very careful though to only buy a rooted tree, rather than one which had been cut down. Then, after Christmas, he'd plant it out in the front garden, so that it could be dug up again and re-used the following year. The gardening books always said that it couldn't be done, as fir trees don't like being transplanted just once, yet alone from a field, then to a bucket in a living room and finally out into a garden, with the cycle being repeated year after year but my father always got each tree to last several years. Indeed, I think the tree which was happily growing in the front garden when they moved out of the house (when I was in my early twenties) was the same one that my dad had bought from the local greengrocer's shop when I was about 9 or 10!
Like the vast majority of children, I received some of my Christmas presents in a stocking. However it was always one of my mother's old nylon stockings. I thought that all Christmas stockings were of that form and was mystified when I starting seeing Christmas movies on TV where children were receiving presents in woollen stockings. "They're not stockings", I would protest, "They're socks!"
