This is another story told to Marisol by a nanny who was from the Andean province of Ayacucho. The nanny told her that as a child, her relatives always warned her not to get close to parties or gatherings of people in the middle of the fields or on top of hills because these were there to take away wayward children, drunks and gluttons. She warned her that if she was out playing the hills and heard laughter and voices, she was to run away immediately and not get close to the table, no matter how delicious and abundant the meal or how inviting the people because if you ate any of the food or touched the guests, they would take you to the afterlife and the party would disappear and all that your family would find on the hill would be a rock.
This story serves to keep kids in line and keep them away from strangers and unknown places. It is a lot like the Irish tales of fairies. There is also the presence of a magical mound which can be found, most famously, in Irish fairy folklore.
