Figuring that indeed, they must be talking to you, you walk down the hall, pausing before each door, trying to decipher what might be in each room. More attendees continue to shove by you, and you hear a gruff "ahem!" come from the speaker system. Yep, they're definitely talking to you.
You open the door you're standing in front of right then, not wanting to be kicked out of the park for misbehavior. The room you enter seems a bit larger than you would have imagined, and is brightly lit.
You see a family sitting around a dining room table; they seem oblivious to you. They're a young couple, probably in their early 30's, and they have both a young son and daughter at the table with them. Then the voice pipes out of the speakers.
"Welcome to suburbia, where everything is white picket fences and rosy-cheeked children. Where the harsh light of day washes away the darkness within," it says, a happy tone in the voice.
The family takes note of you, smiling broadly. "Hi," says the father, "I'm Will, this is my wife, Laura, and these are our kids, Trevor and Sierra." The children smile and wave, and the wife seems to be giving you "the eye" as she waves to you as well. "You're just in time for dinner," Will says.
Then the voice of the speaker comes back on, "Yes, in the light of day, all seems normal. But in the light of the moon, the true nature of things can be revealed, and sins laid bare!"
The room suddenly dims, and you see through a window (that you hadn't noticed before) a full moon has shone through.
"Dinner time, children!" snarls Laura at you, fangs growing in.
