Other than the religious aspect for those who believe obviously.
To continue with my bah humbug theme I was wondering why people get so worked up about Christmas if they are non believers (which I am). Children's excitment aside why do people place so much importance on Christmas day. Some of the nicest days I've had have been random gatherings of friends/family, lots of food etc but none of the expectation that seems to come with Christmas.
I really really can't be bothered with it this year which is a bit unfortunate considering I'm cooking again.
