What would you do?

Imagine waiting for a train after work.

It arrives and is packed full of people.  You wait for the next one.  It's packed too.

You get on.

The air is thick, and moist.  It smells.  You want to gag.

Arms and faces smash against you.  You try to find something to focus on, until you can get off.

As soon as you go underground, the lights dim.

You see a spot of calm.  It's a tiny spot with nothing moving.

It's a small, tiny woman.  She's sitting perfectly still.  She's perfectly dressed, in a navy blue suit with pearls and white gloves.

On her lap is a small square lunch box.

She opens it, and carefully picks out something to eat.  She holds it with both hands like a miniature corn on the cob.  It's red, It's dripping.

She eats it like a rat, nibbling from one end to the other.  Her mouth is now red.  It looks like blood.

She looks up.

She stops moving.  The woman stares right into your eyes, and smiles.  Her mouth is bloody.

You see what she has in her hands is the lower piece of a human jaw... and what looked like corn is human teeth...
