I care that I have an opportunity to make fun of you for stupid things you say. This is a source of amusmement. I don't care a jot about the current spot price of gold. My gold is mostly in the form of collectables that I would be extremely loath to get rid of. Which was the point: tie up my assets in places my wife could liquidate once I'm gone, and I get to enjoy owning them while I'm alive.
Shame for you your wife isn't so indulgent with you, and that a Challenger isn't really an appreciating asset.
