Whilst I don't in any way intend to come across as patronising, indignant or a killjoy, life can essentially suck on pretty much every other day of the year, let alone the 25th of December.
Nowadays I just consider that particular date (and the 1st of January) just another day like any other, and try to appreciate and make the best of life as it comes, even if the festive seasons for me personally these days aren't a patch on what they were when I was younger.
But I fully accept that times and circumstances (both personal and general) change, and like it or not, that's a fact of life.
