I sympathise; historically I've always preferred packing (done at high speed in a vast panic, and enjoying the challenge of tesselating all the little bits) to unpacking (dragged out over months of not quite knowing where to fit everything), but this move recently has been the first one where I've shared the perspective you describe above.

Packing other people's stuff, however, I find positively enjoyable. I LIKE the tesselating, and I like how easy books are, and I like how satisfying it is to watch the empty space grow around you, when it isn't your space. Clearly we should have some sort of barter system where we throw small packing parties and pack each other's stuff by turns :)
