try nyo na lang kausapin ulit. pakita nyo yung plane tickets sabihin nyo none refundable yun at cheap tickets. sabihin nyo na hindi nyo naman kasalanan kung nagkaron ng typhoon at na-iba ang schedule ng exam. if they still will not allow it then i-absent na lang ang bata. the trip is more important than the exam i think. parents should know what is better for their children than the school di ba.
