You need to take a walk.
You're in a bad part of town, but you can't stay stuffed up in this apartment building anymore. Something about the air is making you cough, making you nauseous.
You walk out your apartment and enter the elevator, pressing the button for the bottom floor. You lean back against the smooth wall of the elevator as it lurches down. You're gonna have to stop taking the elevator soon, you remind yourself, this thing is probably hanging on by a thread.
On the floor under yours, the elevator stops to let someone else on. The door opens, and reveals three men- one hooded, wearing a fabric black mask pulled over his face and neck with a red frowning face painted on, another wearing a white porcelain mask with simple black features, and a third, younger man wearing a mouth guard and orange goggles. Most noticeably, they're all carrying weapons.
Before you can say anything, the hooded man steps into the elevator, the other men following suit.
The elevator begins its suddenly too slow decent down; after a moment, though, its movement stutters. The one with goggles looks to you, his neck twitching a little as it interrupts his speech. "Di- did you do that?" As if on cue, the elevator stops again, and this time, it doesn't start back up. The lights flicker.
