You just got hired to be a janitor for an office building. Not the best job, but it pays the bills. Here you are, in the middle of the night, sweeping the halls. Not bad for your first day.

Did you just see someone in the corner of your eye? No, it can't be. No one's allowed here at after hours.

Suddenly, a drawled voice could be heard from a nearby office.

"Finally, this dump is being cleaned…"

The sentence is completely innocent, but you can't help but feel irked to the core.
