As a child, I used to love Christmas, as a teenager and young adult I loathed it (for some of the reasons mentioned above, excess commercialism, the 'faux' happiness that one is supposed to indulge in, the cabin-fever, the relatives, the historic belief that Christianity had merely hijacked an ancient pagan festival, the frenetic stress to 'make it' happy by adhering to a set of increasingly rigid and demanding traditions…..).
Now, I am much more balanced, easy-going and tranquil about it. In the past two decades, there have been years where I was flying out to work abroad immediately after Christmas, and on a number of occasions, also worked on Christmas Day, too and right through the Christmas period, returning - and not even always - in time for the New Year.
Most of my colleagues were parents with children - thus, it mattered that they were at home, whereas - as I don't have children (and I do think that Christmas is a magical experience for children) it wasn't really an issue for me and I was happy to work through the Christmas holiday while they took leave. (And that, in turn, meant that my wishes were invariably accommodated as I like to have Easter off).
Two things, really, have come to mind as I get older. The first is that people die, and traditions then wither away of their own accord. Some of the stuff that used to drive me nuts no longer does - or can - because the people that used to play a certain role at a certain time on Christmas Day (an uncle coming round for drinks at a very precise x o'clock every Christmas Day and so on) can no longer do so as they are dead. You realise that life is not eternal, despite what you might have thought about the tedium of it all at nineteen, and you look back with a rueful recognition of your youthful impatient self and wish you could remind yourself that taking a day or two out of your own normal routine to acknowledge other people's precious routines (if it makes the people in question happy) is no bad thing.
Therefore, the other thing, re rigid (family) traditions, is that one can craft and create and discard and discontinue them at will. They don't have to be set in stone, especially if you inherit what are considered family traditions which have been set by others; some of the traditions that I personally find tediously time-consuming have been quietly jettisoned, and that serves to knock some of the stress out of the equation, whereas I will maintain some that I quite like.
Re gift giving, I must say that I rather enjoy it. Actually, I rather like matching gifts to people. However, it does require forethought, and seizing opportunity when it arises. This year, I had bought many of the serious gifts I planned to give by September. That wasn't planning - it was more being open to opportunity, as when seeing something that you knew someone would really like, and taking the opportunity to buy it when you spotted it, and then putting it aside to be given at Christmas.
