You're trying to finish this puzzle. You're a long way through. You pick up a piece you hadn't picked before. Perhaps you didn't intend on picking it up at this stage, but somehow it attracts you now. You find a place to fit it, but as you carry on you realize that's not the right place for it. So you look for a new place to fit it, only to be back to square one after a while. You keep that one piece safe and proceed with the rest of the puzzle, fitting every other piece in it's rightful place. You see a picture forming. But somewhere in your head the confused state of that one piece continues to nag you. It must have SOME place in this picture. You pick it up again. You obsess over it, trying everything you can to make it a part of your picture. You take a few pieces out. Maybe you got it wrong in the first place. Maybe the other pieces are misleading you. That one piece feels so right there is no way it can't be a major part of the puzzle. You take other pieces out and try to place that one piece somewhere more important. Maybe you underestimated it. Maybe it's much more important than you thought. You struggle. That one piece doesn't leave your thoughts. That one piece you found intriguing and integral now begins to haunt you. You just want that one piece to find its place in your puzzle so that you can move on. You pluck pieces out and you adjust pieces in, but all you find is a trembling tower of puzzle pieces and an unfinished picture that is, at this point, going no where. You stare at the tower as it falls down and turns to rubble, you see a picture, now distorted and unclear, and then you look at that one piece. That's when it hits you. Maybe this piece is not a part of your puzzle. It doesn't fit in anywhere regardless of how hard you try because it doesn't belong here. You want to keep it safe, but fitting it anywhere in the puzzle would lead to a distorted image. You put it away, hoping it finds a way into your final picture. If it really does belong there in the first place. You clear the rubble and start your puzzle again. Eventually, that one piece stops haunting you.
