It's Friday today. Kate and her grandma go to the supermarket. They go thereby bus. Kate's grandma buys some fruit. She buys a blue dress for Kate, too. Blue is Kate's favourite colour. Kate likes her new dress very much. She's very happy. Mary is Kate's friend. She's at home. She's sad now because she can't find her toy bear. She lost it. Mary's father is not happy because his daughter(女儿) is sad.
