Slightly related, but different.
This is a story that my DH related to me. He was born abroad and has an adopted sister, I don't really know the entire circumstances around the adoption.
My DH tells me that shortly after she joined the family (she would have been about 11 or 12 years old at the time and he was about 13) he remembers going out for a meal at quite a nice restaurant.
When it came to dessert his father asked what she would like. Apparently, she was embarrassed but admitted that her family had not really gone to restaurants but when they had eaten out, they couldn't afford to go to the sort of place that would have dessert.
Then, according to my DH, his father ordered every single dessert on the menu for her to try. Not expecting her to eat all of it, or even much of it, or even to sample all of it. I think it was more of a statement by way of saying something like "Don't worry, you won't want for anything"
They were maybe, in their country, sort of upper middle class so, not rich, but his father was always very generous and thoughtful of others.
