dust in the wind

i was at the post office. i got my mail from my PO box and sat in the car for a few minutes looking it over. my window was cracked, and i was listening on my CD player to "dust in the wind" by kansas. there was a guy standing outside the car next to me. he looked like he was just standing there; i didn't see anything in particular that he was paying attention to.
halfway through the song, i began to drive away. the man swayed a little, mouthed something - i could tell now he was swaying to the music, and mouthing the words - and as i drove away, he got into his car, looking a little disappointed (and my interpretation was that it was due to losing the cool music).
