Christmas is easy.
Amazon wishlist.
Steam wishlist.
Other site wishlists.
Stick the links to the above in a Google Doc which contains the line "And a jumper with a reindeer" and share it out to everyone who wants to buy you something.
Make sure there's big expensive gadgets on there. And tiny silly things. And a DVD for Auntie Joan who doesn't know what to get so your brother buys you the DVD and tells her that he got you something from her.
And then anything off-list is basically potential eBay material. Sorry, guys. That's the truth of it. So much so that when I buy others gifts, I make sure to make it clear that - so long as they enjoyed the OPENING of the gift, the surprise, the joke, or the initial tinker - then that gift is theirs to do with as they will, even re-gift, and no shame.
One year I bought a particularly troublesome teenager an Amazon giftcard and stuck it in a plastic maze which you have to solve before you can open it up to get to the giftcard. It became a running joke (especially after she opened it up and then THREW THE GIFTCARD AWAY not realising what it was) and that box went round FOUR other people (family, friends, friend's family, etc.) with differing contents before Boxing Day actually finished.
But, yes, I get the "I'm feeling old" bit. I've been middle-aged since birth but - Steam games? Meh. All remakes and junk indie games and overpriced AAA titles. TV seasons? Nothing I can think of that I would want, even with free reign over all of Amazon and Google Play. Gadgets? Nothing enthuses me there any more and I'm quite happy with my current phone and laptop.
Nowadays, it's the junky toys, the childhood things I never had when I was a kid, and the stuff that makes me laugh that I ask for.
Christmas is about having fun, enjoying yourself whatever religion (or no religion, like me).. Socks don't do that. Serious things that you "need" are no fun at all. And if I need them, I've probably already bought them.
No, I want toys and junk and noisy things and science experiments and board games only hilarious when everyone is drunk, and all the tut in the world - of which I'll only be playing with the boxes from the day after. That's what Christmas has always been about, ever since I was a child, and I see no reason to break with tradition.
If I'm going to have to drag a dead tree into my lounge without needing to provide an explanation, I can damn well have some silly toys too without having to pretend to be an adult.
