Once, some wicked elves lived in a forest. They teased travellers and called them ugly names. Sometimes, they even hid in a tree and threw stones at them. One day, a wizard was passing through the elves’ forest. The elves threw pebbles at him and called him, “A monster!” The wizard was very angry and he cast a reflective spell on the elves. That day onwards, whenever the elves threw stones at someone, stones would fall on them from nowhere. If they called anyone ugly, they would themselves become ugly. Soon, all the elves looked like ugly, old, horrible monsters. They were all shocked and worried. “Who is making us this way? Who throws stones on us?” they asked one another. Soon, they stopped troubling travellers. Some even helped the travellers find their way out of the forest. The wizard understood that they had learnt their lesson, so he removed the curse. The elves became normal but were never wicked again.
