The phone woke Kim up. She was expecting HER mother to call but it wasn't her. The voice on the other end of the line sounded familiar but Kim COULDN'T remember who it belonged to. "Hello," the lady said. "Can I speak to Mrs. Len?" "I'm sorry but she's not at home. She's out. She IS WALKING in the park." It was very cold TO WALK out-of-doors and everything WAS COVERED in snow but Kim's mother walked in all weathers. She believed that it HELPED her keep fit and gave her extra energy. She actually looked younger than other WOMEN of her age and that was probably because of her walking. "Can I take a message?" Kim asked politely. "No. I WILL CALL her later. When is she going to be back?" "She normally COMES home at five." "Fine," came the answer and the phone went dead. Kim felt a bit hurt. "It's not polite to break off a conversation like that," she thought to herself. If I WERE older, I would explain to that lady how to talk to people politely."
