What's a cool story plot?

A young aspiring writer wanders into a thrift store and sees an old typewriter seated on a shelf. Although she owns a computer she has a strong urge to buy the typewriter (plus the price is definitely right) so she does. That evening she loads a sheet of paper into it and proceeds to create a fictional short story about a honeymoon couple who move into their first place together. The following morning when she opens her front door to retrieve her newspaper she notices a couple moving into the apartment across from hers. She greets them and learns that they just married ten days ago and were excited about sharing a home together. That was peculiar enough but what really amazed the writer was that they had the same names as her characters.

Telling herself that it had to be a coincidence she heads back into her apartment and eyes the typewriter. Newspaper forgotten on the floor, she sits before the typewriter and grabs for another sheet of paper. Writing another story she soon runs into it in reality. Could this be for real? A magical typewriter for only ten bucks?
