Outside noisy trash truck's brakes screeching to a halt. Trash cans bumping and scraping as they're emptied, then tossed back on the ground. Sounds are fading now as the truck makes it way around the block.
Inside: oil burner kicks on, hums steadily. Crackling sounds emanate from the baseboards as heat is passing through them.
Outside: a dog barks at something unseen to me. On my roof, the sound of little feet scurrying across the surface. Squirrels no doubt.
Another truck outside. Glass shattering as it's emptied onto other glass.
Try this experiment yourself. Take about ten minutes when you can, sit at your computer, listen to the sounds around you and write down what you hear. I think it's a good exercise for writers. If you come up with some sentences that sound particularly good, use them in your work in progress.
