It's the year 788. I live in Wales.The weather is usually good here. It's windy and snowy in winter and it's cold and and rainy autumn and spring. In summer it 's nice and warm.We like to have picnics,but we can't have many picnics in summer,because people can see us.We need the weather forecast every day.We don't want to meet people.
We have a weather witch.She tells us the weather for the next day,but she often makes mistakes.
The weather witch says, "It wont 't be cold.It won 't be cold.It won 't be rainy.The sky won 't be grey.Peple will go to the forest.You can 't go out. "
And we listen to her and say, "We 'll stay at home.We 'll read our magik book. We 'll sit in our cosy armchairs.We 'll sleep in our warm beds. We won 't go out.People won 't see us. "
The morning of the next day is windy and cold, but we say, "It 'll be warm.
We can ' go out. ''
It 's beautiful picnic weather, but we don 't open our windows and in the evening we are very angry. We say, ''We 'll turn the weather witch into a bat. ''But the weather witch says, ''I am sorry! Now I can tell you the weather for tomorrow.Listen, friends, it won 't be sunny tomorrow.It will be windy and cold.You can go out. ''We are happy. We say, ''We 'll have fun! We 'll swim!
We 'll get wet! We 'll fly in the sky!Peple won 't go to the forest! ''
The next day the sky is clear and blue. It 's warm and sunny,but we go out. People go out too. We see all those people and run back to our houses! We find the weather witch and turn her into a bat.
