Uh...?

I remember when a person used a public pay phone it was considered polite to turn away from others and speak as lowly as possible for two reasons: 1. To prevent others from hearing your private conversations. 2. To prevent your conversation from intruding on that of another. Now, no one seems to care whether or not strangers know the size and condition of their underwear or if their breaking up with their boyfriend seeps under and through Walkman earplugs connected to Nine Inch Nails wailing away.
