I hope you enjoy this little story, where a number of people step into, but don't step out of...
The door swung open. The next person in line entered the empty chamber. Dr. Ziegler fiddled with the control panel and the chamber door closed. A buzz filled the room. A light on the panel switched from steady green to flashing amber. A minute later the door re-opened on a barren chamber.
Next was a young girl holding a stuffed animal tightly to her chest. A woman, presumably her mother, prodded her. The girl hesitated.
"I told you, Eliza. One at a time. Hurry!"
The young girl carefully walked through the door. Zieglar repeated his motions. The buzz rose, the lights changed.
The older woman practically ran through the door. Ziegler wondered how many more there were as the machine went to work. Ten more, then twenty. Finally Ziegler saw the man he knew would end the line, Josef, his second in command.
"Is this all?" Ziegler asked.
All the rest entered the chamber one by one. Josef replaced Ziegler at the controls.
"You have the remote?"
"You bet, Doc. I'm not staying for the fireworks."
Ziegler nodded and entered the chamber, eager to be off the doomed asteroid. Josef adjusted the controls. The door swung shut.
