Puzzling

So, does this summer's crop of girly pop feature more metaphorical references to puzzle pieces than usual, or is it just that I am more sensitive to these references now that I can't escape autism in any aspect of my life? (Puzzle pieces are a symbol for autism awareness.)

Miranda Cosgrove:
when I'm kissing you my senses come alive, almost like the puzzle piece I've been trying to find falls right into place, you're all that it takes...

and Katy Perry:
I finally found you, my missing puzzle piece; I'm complete

And how does it fit into this that for the last three months, my mom and brother have been working on a 2000-piece jigsaw puzzle, and on multiple occasions while waiting for a late date I sat down to work on the puzzle, and never once found a piece that connected?

Never...

I guess I should have seen it coming.
