Solution by Ignacio Larrosa Cañestro.


The winks of fate
Are mysterious and
Can end in love or hate
One can leave or stay
Or just follow our destiny
And get a wink from the stars
The story of our life
Is more than just a wink from the sky
In a wink everything can change
Life on earth in a wink can end quickly
