Summary: It shouldn't be hard to write with an automail hand. It shouldn't be hard to move on.
Notes: Written for fma_fic_contest's prompt 10: 'trace' and won first place. Thank you so much!
Focused more on the mood than an actual, coherent plot and attempted to use the prompt in as many ways as I could; also contains obscure (perhaps not really) references, parallels and symbolism.
And a background ramble to hopefully clear some things up.
