Hi RSM
This is a tough one to review. Some excellent rhyming. There's a great story line in there but I guess with no title or hook to hang its hat on. But I understand from your note it is a work in progress so I'll try to be brutally honest
(keep in mind I might also be FOS)
I think "young" and "girl" are redundant sugg drop the "young" - maybe "worried"?
We don't know why her legs and arms would be sore/aching?
The second verse seems to open in present tense, so - was he injured in the first verse too and you just didn't mention it? Just noticed everything is in present tense - would sugg a switch to past tense from 2nd verse on.
Sugg drop "corner" in the second verse - we already know that.
In verse 3 maybe use "front" in place of "trench" and maybe find a replacement for "young girl"
This line seemed comical to me:
And none of their three legs are sore
I guess you need to walk a fine line here and not make light of a missing leg..
I like Allan's idea of a generic love chorus.
Please don't hate me - there's an unpolished gem here.
