The shop’s door opened with a gentle “ding”. A teenage girl walked in, looking around, getting used to the cluttered dark room. On shelves, all sorts of unusual items were put for sale: a wooden pigeon, an engraved locked box, a teddy bear; unsophisticated at first, each one contained a special purpose.

“The all-knowing glasses? Is it like Wikipedia?” she stopped in front of round glasses in a golden frame.

“Nearly”, the shopkeeper replied,” but you can’t have Wikipedia transmitted directly into your brain.”

The girl laughed. She kept walking until she found a shelf with sealed empty bottles. Just looking at them already felt unusual, like nostalgia.
