### Theory:

‘But if they went away, why should there be any ghosts?’

‘Because – Grandfather says – during a terrible storm one of the houses was hit by lightning and everyone in it was killed. Everyone, including the children.’

‘Were there many children?’

‘There were two of them. A brother and sister. Grandfather says he has seen them many times, when he has passed through the ruins late at night. He has seen them playing in the moonlight.’

‘Wasn’t he frightened?’

‘No. Old people don’t mind seeing ghosts.’

Usha set out on her walk to the bazaar at two in the afternoon. It was about an hour’s walk. She went through the fields, now turning yellow with flowering mustard, then along the saddle of the hill, and up to the ruins.
Explanation:

Binya was still not satisfied. She asked if the people have moved away, then why would ghosts be there.

Usha said that according to what grandfather said, everyone, even the children were killed hit by lightning in one of the houses.

Binya asked if there were many children.

According to Grandfather, two siblings (a brother and a sister), used to play in the night and that he saw them many times.

Binya was amazed and asked if Usha's grandfather was not afraid of ghosts.

Usha said that old-people did not have much fear.

Usha started walking for the market at around $$2.00$$ pm. She had to walk an hour to reach the market. She walked through the mustard fields, then through the ruins.
