"I don't think I can study anymore," complained Geiger. His friends ignored him as they continued to pore over their textbooks.
"The test is tomorrow, G," Roentgen finally replied. "You should be grateful that Dr. Tesla gave us an extra day to study."
"We should reward ourselves for our hard work with a trip to the Cupcake Factory," suggested Curie. Before her friends could reply, the fire alarm began to blare and the lights began flickering on and off.
"Fire!" shouted Roentgen. "Let's all line up and get to the fire exit." He watched closely to make sure all of his friends were following him to safety.
"It's every man for himself!" Geiger said, with panic in his voice. He shoved his friends aside and slammed the door in their faces.
"What a hero," said Sievert sarcastically as she held the fire door open for Roentgen and Curie. "He didn't even wait to see if there is a real fire. For all we know, this could just be a fire drill."
"Either way, we need to follow safety procedures," Roentgen said. "I hope Geiger makes it to the parking lot safely."
"I can see why Principal Hertz made you safety officer," Sievert said. The three friends arrived at the parking lot and looked around expectantly, but Geiger was nowhere to be found.
"Well, kids, the fire alarms are malfunctioning," Principal Hertz told the group a few moments later. "I'm afraid you'll have to stay out of the building for a while."
"I think we should take Curie's suggestion and study at the Cupcake Factory," said Roentgen.
"Sure," Sievert agreed with a smile. "We deserve a treat for staying calm in a serious situation."
"Maybe Geiger will find us there," said Curie. "Although, he probably won't want to face us after he abandoned us in the middle of a fire alarm."
"If he does show up, we are definitely making him pay for our cupcakes," Roentgen said with a grin. "It's the least he can do."
