A city is loud

From our apartment we can hear the periodic comings and going of the Metra train, including garbled announcements, and the honks of outgoing cars across the street, alerting pedestrians on the sidewalk of their presence. Seems like nearly everyone in our building has a dog and if they're out for a bathroom break in the rocky courtyard below, the dogs like to bark up at the windows when they hear us talking.
Out and about on the streets or in a diner people talk with their friends on speaker phone. The conversation you overhear from someone on a phone is no longer one-sided; both sides are for all to hear.
