You have described the role of the teacher so well and I like Your reflections on the place in Your life that all Your students occupy and how important it is to find an approach to each of them. Children always sincerely show their attitude to the people they respect and love. These little colored sheets are notes as a token of appreciation to You. They feel You very good and kind person. I wish You great success on Your difficult path in the field of education and upbringing of the younger generation. I am sure - You will succeed :). Good luck, @gailbelga !
