For the past few years, I've been to a friend's house for tea on Boxing day. If we're at home that day, I arrive late. You've got to get your priorities right.
It also lets me wear my Bah Humbug hat at the match. Christmas - hate it, with all the false "goodwill to all men" shit that accompanies it.
I've never seen the point of going shopping around the Christmas period. All you get in the sales is the same old tat that the store couldn't sell throughout the year, but at a reduced price, so they can bring in the new stuff when they've got rid of it.
