I enjoyed this very short story, and very much hope you expand this world into a much larger body of works. You use words well, and easily conveyed his precarious state despite the mild-mannered way in which she rebuffed him, casually dismissive at first glance, but you know something darker might happen. 

I really liked the way I could see her working at her computer while this little man falls into the throes of desperation. 

More stories, please!
