Moving house sorts your possessions honestly. Some things go in the van and some go in your own car, on the seat beside you, because you cannot stand the idea of them in a stranger's hands. That category is small and rarely expensive. A chipped bowl. A folder of paperwork. A blanket washed to almost nothing.
Appreciation isn't a mood you summon on demand. It is closer to an accurate valuation, and most of us walk around carrying badly out-of-date prices, overrating whatever cost money and underrating whatever took years.
