There are at least two things wrong with your statement.

"Nobody cares if you're dead" is a very sad statement. Hopefully my wife and kid would at least notice.
My brother, who has a Ph.D. in pure mathematics, says that all a doctorate means is that you've learned to talk a lot.
I don't and never will have one, so this is the only relevant information I have.
I didn't begrudge her the right to be warm, but it did make the cups look a lot less pretty. The ones I had were shaped differently, but basically this:

I got them at a thrift shop, so no clue what brand they were. I think I technically still have them somewhere but have only used them once any time even remotely recently.
I used to make, consume and share a lot of frozen beverages. I had a set of aluminum cups that I loved, but everyone else hated them because they started frosting over as soon as the frozen drink was poured in. My then girlfriend, now wife, would only use them with a towel wrapped around them for insulation.
I once posted this picture in response to someone here on lemmy and they responded "I've got that book right behind me." (Possibly paraphrased)
Thank you for putting in the work!
When do the blondes, brunettes and redheads show up?
Gotcha. I wish you luck with your quest.
I've not used it myself, but I've heard good things about KDE Connect, which supposedly can do this and has no controversy of which I'm aware. (It does not require KDE, apparently.)

It's important to note that I said "wrong," not "incorrect."
