Trashed

I found this crumpled up
piece of paper the other night
in the parking lot I always use
behind Davie Street.

A range of emotions passed over me on seeing this smiling face ... torn away from someone, perhaps, that made him happy enough to smile like that.

I glanced about to see if I could find the other pieces to this puzzle. I heard nothing heard and saw no one.

I may have felt compelled to pick up that ripped up and discarded piece of paper merely because it was unsightly litter, or was there something more to it?
