Trapped In An Elevator
trapped in an elevator: the meme
The good news is, there's plenty of oxygen and cozy floor space. The bad news is, you're now stuck in an elevator with someone you a.) don't know, b.) don't like, c.) can't imagine making it out of the elevator alive if you could only find a sharp object. How you got here doesn't really matter, because the fire department's going to be another eight hours. Assuming they've even been alerted to the problem, because that pesky emergency alert button zaps anyone who gets too close.
Better get comfortable.
