Another man's noise

I’m walking away from leaving Coral at work. I cross the street. And I walk.
This section of roadway is being repaired. A jackhammer blasts near me.
A couple of trucks are delivering a load, their engines idle.
The men roll their squeaking handtrucks past.
Another worker closes the back door of his delivery van, it rolls and slams hard.
Yet another truck inches backwards… beep beep beep beep beep.
In the distance a siren.
The sounds are layered into each other, they make a strange music. Something atonal and rhythmic. Really loud, really in my face, really forceful. And amplified by the tall canyon of buildings surrounding me. It’s too much all at once. It’s a parody of itself, and it makes me laugh.
Then, a pop. Slap-pop. Slap-pop. Pop. Pop.
I’ve ventured accidentally into greenery and shade, and a cement wall and a ball.
Tennis anyone?
