Who doesn't love a good phone conversation and who doesn't love a big laugh or two when talking with a good friend? (Yes, young people, humans have had long yak sessions on phones before the invention of the microchip and touch screens.) The problem these days, is, you just don't know if it's more than one person on the other end of the line anymore. But don't let me scare you off. Feel free to say whatever you, make fun of anyone you want, crack a joke on any body or organization you want. But . . . shhhhhh! . . . don't say it too loud!
