When I was packing up my college dorm room at the end of senior year, I found a typed short story and started reading. It was the most peculiar sensation, because it read like I had written it, but I didn't remember writing it. Then I realized (i.e., noticed the heading and saw) that it was my brother's story. Three years apart, we'd picked the same kind of IB senior English project and attempted to write in the style of the same author, and our writing (though in very different stories) was very, very similar.
