I don't bother with Christmas nowadays, partly because when I was a teenager our Christmases seemed to turn into an episode of Eastenders, partly because I don't get invited to family Christmases any more, and partly because I just don't want to.
As an 'outsider' to Christmas it all seems to have got out of control - there seems to be too much emphasis on hosting the 'best', most extravagant event ever which I think is largely to blame for some of the stockpiling of food - better to waste it than the possibility of somebody thinking you've provided a poor spread.
I think it's got far too material now, when I think it should be a time for people to get together and get on in an amicable fashion. It doesn't help that it's rammed down everyone's throats from about October when Christmas doesn't even begin until Christmas day itself; by the end of Christmas day everyone is absolutely sick and tired of it, the shops move onto promoting the sales and move away from Christmas, which technically doesn't finish until 12 days later.
