Oh god, no! I hated jigsaw puzzles as a kid. I was fine with the fact that not all pieces fit; that was the point of a puzzle. But I was really annoyed, not to mention angered, by that "so close, yet so far away" factor, where two pieces are just a millimeter off from fitting together. Forcing them in didn't work. So I took an what I thought was an ingenious measure: scissors! If two pieces were almost fitting together, I'd just trim the "male" piece by a millimeter or so, just enough to make it fit. I ruined two puzzles this way, before my parents stopped buying them. I hate jigsaw puzzles to this day, just because their pieces are "so close, yet so far away".
