How the world fell apart

The Dome

                         Today's Victim: Mike.
          Now, something I didn't tell you. The people attending this school are the last people left on Earth. And now that Mike is dead, there's only 18 humans left. The students are taught by robots.
           50 years ago, aliens came to the Earth and killed all but 200 people, who all crowded into a dome city. We have an agreement with the aliens, we won't go into their territory if they stay out of the dome. They can only come into the dome once every human has died.
            Everyone knows they have a maximum of 17 days left to live so they just try to forget about everything and hope they're not dead tomorrow. Everyone is living their last days the best that they can.
But, someone will die tomorrow. And it might be you.
Now that you understand everything that's occurring, let's focus on the Crazies and how they're taking everything.
The Crazies had a secret meeting at Tabitha's house so that Carsyn wouldn't find out what they're talking about.
"I think she'll probably kill us last," said Serena. "She's pretty crazy, but we're her only friends."
"You might be right Serena, but everyone else avoids her, and if one of us gets her angry, she's probably going to kill them the next day," said Henry.
"This lasagna is good Tabitha! How do you make it?" asked Chris.
"Shut up Chris. This isn't the time for that," said Rhonda.
"Uh why are you wearing a winter coat and snow pants? It's 83 degrees outside," said Henry.
"Can we get this over with? I have things to do!" Annoyingly said Marla.
"Marla go away the only thing you have to do is sit at home claiming you're doing something of significance. Go home," said Henry.
Tabitha knocked over a glass sitting on the table next to Marla as she stormed out of the room.
"Marla! I can't believe you'd knock over that glass! You're so mean!" Exclaimed Tabitha.
"Sorry she knocked over your glass, Tabitha," Gretchen apologized, she apologizes an awful lot by the way.
"We'll help you clean it up," said Rhonda.
"Thanks, I still can't believe she broke my glass like that!" Tabitha said.
"We need a solution to Carsyn before she causes the human race to go extinct," said Serena.
"We could kill her!" Chris said, proud of himself.
"Sorry Chris, but you know we can't kill Carsyn, it just isn't possible. You know, with her being a hybrid and all," explained Gretchen, "the only way she can be killed if another alien/human hybrid kills her, and she's the only one."
"Looks like we'll have to find another solution and we're going to have to wait and see what the next few days have in store for us," said Rhonda.
"Does anyone want cookies?" Asked Tabitha's mom-bot.
"No. We were just leaving," said Rhonda. "Let's go."
They left Tabitha's house and went home to their mom-bots.
"I want some cookies, mom-bot," said Tabitha.
