[Chelsea]

What does this guy mean about this song lyric he put on Facebook. He put when I'm old and wise, heavy words that tossed and blew me, like autumn winds will blow right through me, and someday, in the midst of time, when they ask me if i knew you, I'd smile and say you were a friend of mine. What does he mean by this song lyrics?

[Ian]

an element of regret for words that were heavy (probably towards [with] an old [ex] Friend of his)
anticipating a future time when he would [with experience] look back at the time.
"and with pleasure state he was a friend of him"
> Nice words
