This happened when i return to Oaxaca from Puerto escondido, It was late like 3 or 4 am, my uncle, a friend of him and me, we was sleeping in the truck in front of a kinder, we sleep in the way because they are so tired and could be dangeorus, well, we are sleeping when we hear a child, but we think don´t care because we think someone be around but in a couple of minutes we hear 2 or 3 childs pleaying with a ball, in that momen we look around and didn´t see any thing, we was freaking out, the most faster as we can we turn on the truck and drive direct to Oaxaca.
