I am the boxer

I am just a poor boy
Though my story's seldom told
I have squandered my resistance
For a pocket full of mumbles, such are promises
All lies and jests
Still a man hears what he wants to hear
And disregards the rest
...
In the clearing stands a boxer
And a fighter by his trade
And he carries the reminders
Of ev'ry glove that laid him down
Or cut him till he cried out
In his anger and his shame
"I am leaving, I am leaving"
But the fighter still remains, mmm mmm
Simon and Garfunkel, 1969

Possibly their greatest song both for its music, its lyrics and its truth. Paul said "I think the song was about me". Me too. What if the promises I believe in are a bunch of mumbles? If they are not then to say so is rank blasphemy and there's the rub. And that last stanza - how strongly it resonates with my experience. Where would I go? But the fighter still remains!
