1) Three friends are going from house to house ‘trick or treating.

2) The writer wanted a few more chocolate bars. 

3) The writer didn’t worry because the writer believed they could take a shortcut home through the old forest. 

4) In the forest, the children got lost and then it started to rain. 

5) It was dark and foggy. 

6) They decided to stay because it was very late and because everyone was cold and wet. 

7) When they went inside, they started to eat their chocolate bars.

Voilà :)
