Hahaha, wow. I cannot compete with these. My strangest thing was a game to a console I don't have.
My SO is thankfully as non-materialistic as I could hope for, and I have to remind myself a lot of people have "giving things" as their primary love-language. Every year, I care about "stuff" even less. Newer friends, family, and acquaintances sometimes try to get "the thoughtful thing," but there's almost no stuff at all that either of us want. I'll donate and return gifts for more savings if it lets people feel good about "giving a thing," but at this point I would be good with nothing at all.
I love buying presents for people, because most people want stuff, and I remember "favorite thing" hints handily. It really is cool to see people genuinely delighted that you remembered something obscure, but Amazon makes gift-finding pretty boring. I wonder if it wouldn't be possible to convince givers that some of us are really fine with cash, or a donation to charity in our names. They gently remind me "no way," and we keep opening aloe-infused socks.
