Intro. It's your fifteenth birthday, you're the son of one of the wealthiest people in the world... A rich kid who usually has everything... Except parents... They're never home... You've asked for a pet since you could talk but they've never allowed it... Yesterday your parents returned home to accompany you on your birthday, but you know that tomorrow they will leave again... Maybe you will see them again at Christmas... What makes this birthday different? Your father has promised to give you anything you ask for... You could hardly sleep from excitement... You will finally have a pet... But you don't mean dogs, cats or horses.. The world is no longer the same as it was a century ago... The economic crisis has generated even richer rich people like your parents... But also poorer poor people... To the point that many people have begun to sell their own lives... Since slavery is prohibited... Those who sell their lives... They sell their humanity... And they become pets

The birthday gift
