I like all the seasons and appreciate the dark, cold time of year. I have a warm coat, a decent umbrella and waterproof boots and I do a lot of walking in winter. The lights and decorations fill the gap filled by sunshine and flowers in other seasons.
We don't decorate much beyond the tree, but my tree is a thing of beauty. I'm an expert charity-shop rummager and have collected all manner of traditional, Victorian-style baubles in red, gold and green. I like hunting out a couple more each year. Other than that, we just have holly, ivy, mistletoe and a string of cards. Not a lot of effort to put up and the cost each year is small. I love seeing the house dressed up.
I'm a hobby artist and a crafter, so I sit down in early December and draw my cards for my nearest friends. I also enjoy making a few little gifts for friends and something a bit more elaborate for my partner - but crucially no one expects me to do this and there's been years I didn't get around to it and that's fine.
I like all the events: festive get togethers, carols-by-candlelight, the solstice, my mother's incredible Christmas Eve party, Christmas dinner with immediate family, Boxing Day walk. Neither me or DP have to go back to work until after the new year, so after Christmas we hunker down for a week of reading, crafting, gaming and general hibernation, with a few walks thrown in.
It probably helps that my family are all adults and we're all easy going people who get on. Nothing has to be perfect and no one has to spend a lot of money.
