Long ago, Thunder and Lightning lived on the earth. However, they were forced to live on the outskirts of town, away from the rest of people.
Whenever Lightning got angry, he would destroy houses, knock down trees, and sometimes, he would kill people.
Lightning's mother, Thunder, would often loudly scold Lightning for the raucous and destruction he would create. However, Lightning never listened.
The people couldn't stand this anymore, so they complained to the king. As a result, the king sent Thunder and Lightning to leave the town.
Despite this, Lightning continued to destroy and burn nearby forests and farms. The people complained again, so Thunder and Lightning were then banished from the earth and forced to live in the sky so no more destruction could be done.
Today, you can still hear Lightning when he is angry, along with his mother's loud reprimands. But sometimes, when his mother is very far away, her voice is not heard while her son is creating destruction.
