Arrived without an explanation
Mystery Box
One sealed answer. Several unhelpful possibilities.
Final Parcel
Mystery Box entered the depot with a perfect seal, a crooked shipping label, and no declared purpose. Nobody remembers ordering it. The arrows insist on upright storage; the broken-glass mark requests courtesy. At noon it shifts one inch closer to dispatch. By closing time, the tape is still warm. Every clerk has a theory. None has volunteered to open it. The night shift leaves it the good chair.
Depot Wisdom
If the label knew the answer, it would have said so.
Mystery Box
Leave the seal. Keep the possibility.
