You’re putting too much thought into it, IMO.
I have a SIL who works for a newspaper. My BIL has been a GM executive for 25 years. These people are dripping with money, yet my kids have gotten recycled and thoughtless obligation gifts from them.
They are just self-centered to the max.
You have disgusting relatives.
Did you not hear the story of how they sent back the Churchill bust?
Sounds like my in-laws.
