First I want to say great poem, and I hope you get more stuff up soon :) If I had to offer some criticism, I would suggest taking out the "who" so that it's "The boy did this" rather than "The boy who did this" because with the latter, it's just a fragment. Which is definitely okay for poetry, but in this case I just don't think it makes sense. Also make sure to pay attention to your line breaks and read through your work several times so you catch things that could be improved. Sometimes just shifting one word down to the next line can make the whole thing flow better. Okay, I'm done being a meanie now :P I think this poem carries a lot of emotion in relatively simple words, which is something that takes talent to do, so congratulations on that. The chronological progression from child to elderly man drenches the whole thing in sadness. I like that rather than transitioning from referring to the subject as a boy to a man, you kept it at boy. That makes it seem like life really just stopped for him. I especially like the second-to-last line, with the comparison of gray hair to the color of his soul. The rhyme in the last line was a great way to finish it.
