Curiosity makes us see the Universe as an infinity gathering of keyways through which we peep like kids.
We cannot open all of them, but we surely keep at hand (in a pocket, purse or on a string around our neck) Empathy the key fit for all doors to the Galaxy of People.
We push the handle using the power of Imagination. And We discover a different room every time. A space so vast and full of small keyways itself, that we can only call it Human nature.
