My family never stopped the tradition of christmas lists when we reached adulthood (It just makes shit easier, and my mother can't be persuaded to just stop buying gifts). But I've sort of reached the age where I have no clue what I would want to be given as a gift anyway. What would you/ do gift yourself for Christmas.
I usually ask for darn tough brand socks. Can't go wrong with a good pair of socks. They're expensive enough that I don't buy them for myself, but cheap enough that it's not unreasonable to ask for 1-2 pairs as a gift.
