They're all sick
I'm at Morning Job™, all alone. All by my lonesome. Apparently everyone is out sick, but I come in anyway. Maybe there's some virus floating around the office. If so, why was I not told "Hey, stay home! Everyone's sick!" Maybe they WANT me to get sick, like everyone else. Maybe they're testing my immunity levels. Well, I guess SOMEONE has to answer the phone and say "No one's here, they're all sick."
