Inquiring minds

If you break a mirror it's seven years of bad luck. But what happens if you receive a broken mirror? Does the luck transfer? Or does the curse land firmly on whomever broke the mirror in the shipping process?

And how would blame be assigned? How many years are assigned to the guy who thought a single piece of bubblewrap would protect the mirror? How much of the curse goes to the guy who didn't mark the package as fragile/breakable? How much to the guy who dropped it? (Or loaded it at the bottom of a stack of heavy items, or stepped on the box, or didn't secure the load in the truck so it fell over during transport, or whatever else shattered the thing into dozens of pieces?)

As a side note, due to a miscommunication on the part of the builder, when I moved into this place there wasn't a single mirror. No medicine cabinets, no mirrors in the bathrooms, nothing, nada, zilch. For the first few days I used the microwave to check my appearance before leaving the house. Eventually I found a mirror for the closet door, selected medicine cabinets for the full baths, and ordered a lovely decorative mirror for the half-bath. The decorative mirror today-- smashed. Sigh.

Well at least I still have the closet mirror upstairs. And there's always the microwave....
