Many years ago, as a Sunday School teacher, I had a student who seemed a little unruly and a bit belligerent — a contrast from his older brother, a model pupil who had also been in my class. One morning as I was hurriedly setting up the lesson plan before the children's arrival, I needed help and asked the younger brother — who had always arrived early — to help me. He plunged into the task, doing a great job. From then on, I relied on his assistance which he was very happy to give. I consistently told him, "You did a good job," "You did that so well," "You are helpful," with no false flattery — something kids can usually spot in a nanosecond — and he displayed no more negative behavior.
