To me, Christmas is just a name for time when we celebrate light in a time of darkness and look forward to better days. Any other name would do as well. I don't think about the Christian aspect because I'm not one. However I do like to use the festival to take time out to tell and show people how much I care about them.
However, it does seem to have become an excuse for spending and it seems that unless you buy your kids heaps of expensive presents and are seen to be 'doing things properly' then it's not Christmas. It's as though the happiness of Christmas can only be measured by how much you spend on it and how drunk you can get during it.
I've certainly stopped making a huge fuss for Christmas. As long as I get some time to relax with my family, the rest of it can go sing. You can't relax if you're only bothered about how good your table or your decorations look, or whether you've cooked enough sprouts even though nobody likes them.
