“Come quick! I just saw something entering the neighbor's house.”
“A burgler?”
“No, something. Nothing human. Come on!”
“Okay! Okay! I'm coming. Where?”
“See where I'm shining the light?”
“Yes. It looks like a screen is falling out.”
“Yeah! That's where I saw and heard movement when I was taking out the garbage. Some … thing … scrambling to get in.”
“Might be a squirrel.”
“It could be the start of an alien invasion!”
“Really? It's a squirrel, or maybe an opossum [1].”
“Or, you know, the return of the Demonic Creature that invaded Bill's Room [2]!”
“Now you're being silly.”
“Don't say I didn't warn you.”
