I am never bothered by what people have, nor impressed by big houses, cruises, big cars etc.etc. Never have been. I'm impressed by happy children, a happy marriage, a healthy lifestyle and a cosy home, a beautiful picture, good food, a beautiful garden, nature, animals, scenery, sunshine, someone who can bake, and a decent, kind personality.....
If anyone boasts to me about what they have [bought with big money] I am amused and look for the reasons this person does it. Poor upbringing with no manners? lack of self awareness? feeling inadequate? thinking money buys happiness? trying to make the other person feel inferior? copying someone else? feeling smug ? making up for a miserable life?....or genuinely wanting to share good luck/prosperity and include the other person by asking them to share whatever it is they are boasting about?
The last option is fine. If for the other reasons I would avoid that person.
A relative used to boast year in and year out about countless holidays abroad ad nauseum, looking down on me because I didn't...so tiresome and I avoid her.
