This COULD be so touching--it caught my eye and my heart--- I think I know what you mean--
For me , the weakest section, ( after an intriguing and poignant intro--) was-----
" but could i play a song for you--
could i do a thing, or two
i'd do them all,
but we know how that works
just like when i "help" and make everything worse"---
that last line in particular seems a bit weak----tweak it please--YELLl, don't whisper or muse-----say what you mean--- and this will be a truly meaningful write.
