Jigsaw

I put the puzzle together but there were pieces missing.
So I looked for them.
And looked.
And looked.
And looked.
And I think I found some that were pretty close to perfect.
But they belonged to another puzzle.
And I couldn't bear to steal them away.

So now I'm trying to fit some other pieces in, but they aren't really the same.
Except I have to make them work.
They're my only option.
And I need to finish that puzzle.
