the buses are singing

from where i live now, you can hear a bit of traffic out the back. my home is on a corner intersection, one that gets a lot of cars, firetrucks with their sirens wailing, and buses.
in the summertime i'd go walking along the quiet streets and then i'd hear the singing. i didn't know what it was and i'd try to catch if it was a radio, someone playing their flute....and i'd try following the sound. never occurred to me that there were more songs during rush hour.

and then i figured it out.

as the buses come around the corner, they stop at the stop sign. as they proceed through the intersection, they have to turn left or right. when they turn left, a cross breeze catches their bodies, and makes a light toooOOOOOooooooo. and then you hear the gears shift.

never thought i'd hear anything beautiful in the city. but there you go.
