After watching the disturbing live news clip, you hear a knock at the door. You grab a kitchen knife and look through the peephole. You release a sigh of relief. It was your neighbor from the apartment to your left. You look him over.
"Have you been infected in any way?" you ask him.
"Not that I know of. I just got away from my friend who had been infected. I managed to evade him, thank God."
You look over him once again, then open the door. Right after he gets in, you close, lock, and latch the door.
