When his parents have announced that they were going to be away for the weekend, sixteen-year-old Marvin thought,’This is going to be the best weekend ever!’ He couldn’t have been more wrong. After Marvin's parents were gone, he called some friends, but suddenly the electricity turned off and the signals wavered. He thought of trying tomorrow, but next day, again, he couldn't call his friends. He set out to his best friends, Josh, when a dog gave him a chase. He was lucky to be able to climb up on a tree. When it was safe, he climbed down and went home. Inside the house, he sat in the armchair and thought, why do all these bad things happen to him!
