Farah was sitting in the kitchen going over the party list with her mother.The exams were over and Farah wanted to invite her friends for a party.
“Farah，aren't you going to invite Hafsa？”her mother asked.Hafsa had been her best friend since childhood.
“Mother，you know I am now a part of Purple Girls Club and we have some rules about people we can be friends with，”Farah answered.
“Really？And what are the rules？”her mother asked.
“Well，only very pretty girls can be part of our group.And Hafsa is so...you know...dark.”
“I cannot believe it，”her mother said angrily．
As Farah left the kitchen，her father called her from the living room.
Farah went to her father and paled when she saw the exam report in his hands.“Farah，what has happened to your grades？You have failed in Mathematics，”her father said.
Farah had no answer.The truth was that the activities of Purple Girls Club left her with very little time for studies.
“Farah，it says that you can take part in supplementary exams(补考).If your grades don't improve then，I'll cancel(取消) your trip to Spain.”
Farah went to her room and called Gina，the leader of Purple Girls Club， “Gina，can you help me to complete my notes before the exams？”
Gina laughed.“Exams？Who cares about exams？”
One by one，she called her friends in the club but no one seemed to care or wanted to help.
Farah knew Hafsa would help her.Farah also knew Hafsa had been hurt by her，but Hafsa said，“If you need any help，just let me know.We can study together till your exams.”
Next Monday，as two friends entered the school together，Gina called out.
“Farah，you know our rules.You cannot be friends with those who do not belong to our club.”
“Gina，I have a new rule about friendship，”Farah replied.
