She was kind and nice."Good morning, children," she said and smiled. The lesson began. But the pupils didn't do what their new teacher said. They spoke loudly and ran in the classroom.Suddenly it became dark and very cold for a minute. The pupils sat still at their desks and looked at Miss Chatter.Their new teacher took Oliver's pen, looked at it and said: "Three, two, one!" The blue pen became red and turned into a nice red umbrella. Miss Chatter took the umbrella and touched Oliver's chair. The chairs began to dance with the children sitting on them. Oliver was happy.
