What does this guy mean about this song lyric?

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 mine. What does he mean about this song lyric? If it means anything
