“Hi, Mo, it’s your favourite exam today” said Nima as she arrived. Terry looked back again. “What’s wrong with her?” said Nima. “I thought you were friends.” “Yes, so did I,” said Mo. “but she hasn’t spoken to me for two weeks.” She promised to help me revise for the physics exam, but then she ignored all my calls and texts. And when I rang her house, her mum told me she was busy. She doesn’t remember who her friends are!” said Mo angrily. “Are you listening Maureen Quinn?” Mr Reed was talking to the class and the other students were going into the exam room. Mo gave Nima a worried look and followed them.
