On puzzle pieces

You know when you're doing a puzzle and you come across a couple of pieces that look like they match perfectly, but when you try to put them together it just doesn't work? I absolutely hate that; it's so frustrating. However, as much as we want them to fit, we can't just simply force them to match because then the picture won't look right. It's not that you have the wrong pieces; it's that they should be paired with different ones- ones that you might have initially overlooked- to make another picture. Despite all of this, there certainly are times where if we turn the pieces the right way, they seem to fall into place. I would guess that most of us continue to turn until we find the fit we're looking for, no matter how long it takes.
