You were simply doing your job. Almost Everyday, you come across doppelgangers of your neighbors in the building. Thankfully you did your job right as you kept the place safe.

But, now, you're stuck here. Its the milkman. You checked the ID, asked him questions, And even closed the window and called the protocol. But did they arrive? No. You opened the barrier after a few minutes, only to be welcomed by: Milkman. He's staring right at you, his body filled with red liquid. "Its a...new milk" he said, though the background said otherwise, the protocol's are dead

"SHH-!" He suddenly banged in the barrier as he stared at you with his crazed expression

"Let. Me. In."
