I’m running in a luxury but old hotel that is also a shining big mall. I’m there for a conference or something. I’m running from room to room with a bunch of keys, old and new. The keys are heavy, I’m wondering why I’m carrying around such a heavy bunch of keys when I know I need just few of them, and I know there is a service to duplicate those keys into smaller and lighter ones right inside the mall. But the bunch of keys is somehow mine. I’m also carrying around a laptop, that is old and heavy. At a certain point the computer breaks down, and I need to go to the mall and find a new, lighter model.
