Oh, something I love, which the majority of Mumsnetters posting about them here seem to hate, are blue Christmas lights. I particularly like the icicle types ones hanging on the edge of a roof, on either a slow flashing cycle, or still. I dislike any really fast flashing lights as they make me feel dizzy and ill. I think the reason that I like either the blue lights, or white lights, so much is because I love the look of snow and ice, especially at Christmas, and those lights remind me my childhood Christmases, where really did get white Christmases quite often!
I remember being about 11, and coming outside after attending Midnight Mass (CoE as it happens) with my parents and maternal grandparents, and it was snowing - fat, white, gentle and wonderful snowflakes ❤️ and I have never forgotten that sight, and the gentle, warm, safe, happiness I felt on that very early Christmas morning.
I also love taking my Grand Children to visit houses that have gone over the top with their outdoor decorations. There is a great one in Bristol, and in Rothwell, near Leeds, there is an amazing street where most of the houses have outdoor Christmas lights, and most of them look amazing - when you turn the corner into that street for the very first time, they just look completely magical. They are, of course, still very good on subsequent visits.
Thanks to all of you who make the effort, and pay the electricity bills, you give so much annual pleasure to so many children, both young, and old, including ones like me in my late 60's!
