|Think about Loose Coupling|
My father arrived at Basic Training for the United States Navy in 1952. All of the new meat was lined up, and an NCO walked the line getting basic information. He reached my father, and the exchange went like this:
NCO: "Name: last, first, middle initial".
Dad: "Lappin, Arthur".
NCO: "Have you forgotten your middle name Lappin, Arthur?"
Dad: "No, Chief Petty Officer. I don't have one."
NCO: "What is your CHRISTIAN name, Lappin, Arthur?"
Dad: "I'm a Jew, Chief Petty Officer. I don't *have* a Christian name."
NCO: "From now on, your middle initial is NMI (No Middle Initial)! Now get down and give me 50 push-ups!"
Dad made certain his children had middle names...
