My aunt and uncle are very wealthy and I find them extremely difficult to buy for. They are very generous with gifts for us so I really want to do a good job but I can never think of anything good. They live abroad so weight and size need to be taken into account, although if I find something heavy but good I can wait until I see them. They like art, reading (but books are heavy to post), walking, birds. Nothing for the house as everything is "curated". I just feel like everything I could buy is worse than anything they could buy themselves. Any ideas gratefully received!
