I would like to challenge your readers a little bit.
How far back did all this start? I'm talking about the phrase we hear every day in the marketplace, on the street and in the restaurant. It is: "Hi, guys!"
My wife and I are in our 70s, and whenever we enter a restaurant (the only luxury we will enjoy) the servers come over and say, "Hi, guys!"
My wife looks at me and says, "When did I turn into a guy?"
Did all this happen in the '40s, when women stopped wearing dresses and started wearing slacks?
