it it strange, suddenly having a memory come back out of nowhere. you think you're going crazy; you wonder where this recollection has been hiding all your life. you try to push it away, because you think you've hammered out the whole timeline of your life, but then you see that one extra moment, and suddendly you are breaking apart what you though was a solid segment, and seeing it for what it is: just a string of events, shoulder to shoulder, and a gap where there is room for one more.
