1. Do you write a whishlist? Do you get most of it?
I would have a wishlist, and most of the things I suppose tended to show up, on account of the fact that A, I was an only child, and B, I probably asked for less than most kids, although I will admit, I could ask for something like "Transformers", and be happy with whatever I got. I can fondly remember greeting blokes such as Devestator, Omega Supreme, Optimus, and Jetfire for Christmas, sitting under the tree not even wrapped. No Megatron, though. My parents hate guns.
2. How does the list get to Santa Claus?
If you postmark it to the North Pole, the Post Office will take it and do who knows what with it. I guess kids just assume that Santa has FedEx
3. How do all the presents fit into a sock? 
We had stockings in addition to our presents. It was usually filled with small items, like gift cards, candy/chocolate, cassette tapes, pencils, etc. There was one year where my Dad totally forogt to get my Mom anything for her stocking, and she was really really crushed, and so from then on until my parents divorced, I had a fanatical devotion to making sure both of their stockings were equally filled.
4. Do you leave a small gift for Santa?
Like sprunk said, mlik and cookies. Milk and cookies.
5. Do you sing songs in hope for more gifts?
We have no Christmas songs that relate to trying to get more gifts. When kids want more gifts, in America they just scream and cry until they get their way because trying to buy the love of your children is a national tradition.
6. What is Christmas eve for?
Again, as sprunk said, people go to church. But for the others, families usually set their own traditions. A friend of mine always opens all the presents on Eve with his family. Another opens one. Another always has a big diner with family. For us, we'd drive around and look at Christmas lights.
7. When do you actually get your presents?
As I said last question, it varies, but the majority are opened on the morning of Christmas.
8. Do people really spend hundreds of dollars/pounds/etc on gifts?
No doubt. I'd say $500 is a good average for me.
9. Do you always eat traditional foods like the turkey?
Our Christmas dinners are almost exactly like our Thanksgiving dinners, ie turkey, ham, stuffing, cassroles, pies, and TAMALES!
10. Are all the streets and houses really insanely decorated with lights and props and and fake snow and stuff?
I don't know if I'd call it INSANELY decorated. As far as public locations/buisnesses, it's pretty subdued except for places in town where they have displays, ie sprunk's garden, NY's Christmas Tree, or the Trail of Lights we have here in Austin, nothing's garish or anything.
People decorating their houses, though, that's VERY popular, hence the aforementioned looking around at Chritmas lights on Eve that I mentioned. Still though, it's hit and miss.....some neighborhoods will only have the occasional strand of lights or lit up house, while others spend hundreds of dollars on their displays, with mutli lights, timing mechanisms, sculptures, anything you can think of. Some subdivisions even require that you participate.
