Parents protect. That’s one of the primary job descriptions.
Protection can take many forms. There’s the verbal confrontation, often with another adult, when the child is accused of an infraction of social norms. Providing shelter gives physical protection. Food is basic. Clothing for humans.
And when danger threatens. Sometimes it’s best to flee the scene.
I remember once dashing with my parents and brothers from the baseball stands to the car. We’d stayed for the fireworks. And the rain came down in sheets as the last explosion faded from the sky.
I’m not sure what this family is fleeing. But it looks like one adult is acting as “rear guard” while the other guides the children to safety.
