I recently spent a couple of hours at the DMV; it was time to renew my driver’s license. The place was crowded with, in the words of the old prayerbook, “all sorts and conditions” of people. It was a multiracial and multigenerational melting pot. Around me, people were speaking in a variety of languages, including that version of English I associate with New Jersey. (It really is a different language, I think!) Every imaginable style of dress and undress was on display. People had done things with their hair I didn’t know could be done. Almost all of us were talking or texting or e-mailing on our smartphones.
