There’s always been a saying, an expression of exaggerated exasperation, that’s irked me: “What do you get for the person who has everything?”
The fundamental flaw of that question is that it ignores a very important fact: The person who has everything is probably rich, and you should never feel all that burdened about what to get them. If you told me that you’re agonizing over what to get a rich person, I would ask you to reevaluate your priorities.
