This converted schoolhouse still chirps with the sound of children. A volunteer teacher points at her eye and elicits the English word: "¿Cómo se dice 'ojo'?" she asks the group of 6- to 10-year-olds.
They hesitate and look at one another until one of them gets it, and they join in a collective scream: "Eye!"
It feels like a bit of normalcy for this group of Central American children who fled their home countries and are temporarily living in a family shelter in Mexico City.
