It's about a break up that happened so fast they didn't see it coming.
It's so vivid in those lines:
"Where did we get off the track
What was it that brought us down"
and
"Trouble crept up on us
Warning never came a time
Before I knew it we were dust
Just left behind, left behind"
and
"And after all the noise I never heard our last goodbye
It was silent as a butterfly"
"There was no parade" itself means that everything was fine and there was no warning signs or time for one to prep themselves for breaking up or for losing the person they were with, it's so much like funeral parades.
