She's Not Human

A man sits at his keyboard with blood running from his nose while a woman screams behind a locked bedroom door. He says he needs to explain before he lets her out. He says she is not human.

She looked ordinary when he first met her at a store register. Later, at a coffee shop, they talked like strangers who had somehow skipped the usual parts. Soon she was in his house, in his bed, in his life.

Everything about her seems average. Too average. As he watches her, searches for flaws, and checks his own sanity against the internet, his need to prove what she is begins to take over.
