Control

Her glassy eyes drove me mad.  In a fit of rage, I ran into the kitchen and grabbed the biggest knife I could find.  She said something in that dull, mechanical voice of hers but no longer listening, I slapped her down onto the counter.  I then raised the knife high in the air like a human guillotine and smashed it across her neck. 

Her round plastic head jerked back.  As it teetered on the edge of the counter she cast me one last glassy-eyed look.  Finally her head fell to the ground and rolled across the linoleum floor, unimpeded, until it came to rest underneath the industrial sink.

I set the knife aside.  When I pushed my fist into her dolly stomach, nothing happened.  I had done it.  She was silent at last.
