Puzzle

She's like that puzzle peice,
The one you think will fit.
You slide it over but
See a small missing slit.

No matter the size, it's important,
The way she just doesn't work.
Her eyes convey no happiness,
Yet her shoulders bear no hurt.

Still light shines through that hole.
It's making you go barmy.
Don't criticize, you fool.
She's the one that makes me.
