"This discussion is a perfect illustration of what I constantly tell my wife - you can never have enough cameras, lenses, guns, or golf clubs - oh, and diamonds, according to her! - Texsport"
I like that, but for me substitute watches for golf clubs. A few years ago (OK, decades) I came home with another new Omega watch. She ranted and raved for a week. Finally couldn't take it no more. I said I would take it back - and we would take her diamond rings to the jewelers store and sell them too. Never again has she complained about my "collections".
