I do like Christmas, and after the inevitable period in October when I start to think "What on earth am I going to get X?" I love giving stuff. I can rarely think of what I want though, so the family (me, Mum, sister) end up doing a sort of "What do YOU want?" dance for a few weeks, until we all have ideas. This year, I've gone bonkers - each family member is getting something bought, and two knitted things, and a calendar (made up of my own photos), and little Oli is getting at least two presents, despite only being 5 months old, and one of them is a book! But I don't think I've spent more than £20 on anyone in total, and that includes the wool for the knitted stuff. And I love the food, and the little family traditions (as long as they don't become great millstones around the neck).
Ther's no religious connection for me, really, it's just a nice excuse for a midwinter pick-me-up.
