if you know what luxury means please let me know
There is no simple answer to that, and I think it partly depends on culture. I know where I live (suburban USA) luxury often has to do with impressing other people--conspicuous consumption.
When we need a new car in my family, my husband always asks for the same things: a full spare tire and a radio. That's luxury for him. :))
Exactly my point, I don't know your husband but I already like him. 😅
I hate the idea that luxury is something to impress others. But that the reality. Isn't it?
