Mrs Brown had a daughter. Her name was Lisa. When she was four years old, she had a bicycle. It was red and white, and it had small wheels at its sides, so it always stayed up. Then Lisa did not have a bicycle for a very long time. Now she is twelve years old, and she wants a bicycle. Mrs Brown goes to work by car every day, and she takes Lisa with her to her school and brings her back when she finishes. Her school is on one side of the town, and Mrs Brown’s office is on the other side.
