Valuable; probably a Julian Opie self-portrait which I think is worth a fair bit more than anything else in the house.
Precious; dunno…the kids? Everything else is insured. It would be a shame to lose old irreplaceable family photos but I wouldn’t say there were any that were specifically precious I dunno
Can’t really imagine running into a burning building to rescue anything inanimate …though I’d maybe grab USB sticks and a couple of hard drives on my way out of a burning building
