She was a primary grades teacher and noticed that one little boy was having problems. She asked him if something was bothering him since he seemed unable to keep his mind on his work. The lad confessed that he was worried. His mother's live-in boyfriend had jerked the boy's mother around by the hair the night before and had created a terrifying scene. For that teacher, this was not an isolated incident.
Many children come to school from highly dysfunctional families.
Yet, a teacher is supposed to somehow guarantee that all children learn, and at the same pace. Teaching is a hard and demanding job. Teachers must deal with many children from many situations. Think about your own work. We love it when people build emotional bank accounts with us.
