You can tell an awful lot about a person in the way they handle their luggage being lost at the airport or a valuable package not arriving as intended in a postal delivery.
I suppose it comes down to the thought, "Hey, how could you be so flippant with my stuff as to lose it, or damage it, can't you see how important *this* is?" I guess being a person that travels a lot, I am always so intrigued by the stuff folks lug around with them versus the stuff they check in baggage claim (some grudgingly) and the stuff they just send ahead and even the stuff they leave behind. For me, the most "valuable stuff" goes with me yet, in the event of an emergency, like a crash landing in the Hudson, even my beloved iPhone would be water logged and that little sensor embedded in it would flash the "Sucks to be you, your warranty has just been void and all your contacts you were too lazy to back-up are gone forever...." It's really a matter of security and priorities and it has NOTHING to do with the physical luggage or even the box or art that just got mangled.
If our security was hinged on the stuff in our heads and our priorities were fixed on people, I believe, the perspective would change. At that moment, something truly profound happens, we see the value of the person... even the person who lost the bag or crushed the box; they were the person that taught you the best lesson you could have learned, you can live without the stuff.
