  • "A few of these terms do linger. On the list of “menu options” given me by a computerized answering service yesterday, I could dial 13 for one person, dial 12 for another, dial zero for assistance. Of course, I wasn’t dialing anything. Dialing was what I did in that Irish pub, four decades ago. But when someone’s not really on the job these days, we still speak of their dialing it in. What other language lingers, from those days of switchboards and pay phones? Indulge your nostalgia and let us know. The party line’s open."
