Thank you for your comment @josemalavem yes, it is a reality from which we are not exempt, we all live it, we suffer it, and we have no choice but to bear it, for now. Of course, to see children living in different circumstances is even more painful when their life should be full of colorful and wonderful moments. I am sure that the vast majority of teachers in this country do what they can to disguise that sadness in joy and color when they enter school.
