Text
Last week, my four-year-old daughter, Sally, was invited to a children’s party.
I decided to take her by train.
Sally was very excited because she had never travelled on a train before.
Sally sat near the window and asked questions about everything she saw.
Suddenly, a middle-aged lady got on the train and sat opposite Sally.
‘Hello, little girl,’ she said.
Sally did not answer, but looked at her curiously.
