I touched my locker door and it popped open with a soft metallic click. The inside was sparsely decorated. A picture of Princess Leia posing with a blaster pistol. A group photo of the members of Monty Python in their Holy Grail costumes. James Halliday’s Time magazine cover. I reached up and tapped the stack of textbooks on the locker’s top shelf and they vanished, then reappeared in my avatar’s item inventory.
