What Do I call My In-Laws?

Dear Old Dad

What do you call your in-laws? Let's say I already have a Ma and a Pa, or a Mom and a Dad, and I am not all too comfortable calling anyone else by the same moniker. Let's say the in-laws are the old fashioned types. Let's say they are not all that comfortable with my using their first name and think it too cold if I call them Mister and Missus. What is the alternative?

For example, Mother Ohara is too old fashioned. Father John? Too religious sounding. And not very Jewish. What about padre? Eema? Père? Auntie? Sire? Duchess? Capo? Colonel? оте́ц?

Should they be insulted if I don't call them Mum and Dad?

"Surely son," my future father-in-law may say, "You must feel close enough to us by now?"

Mama

And I might reply, "Yes. Yes, I do. And don't call me Shirley."

While pondering through this dilemma of titles, I started wondering why only the military, doctors, and members of the clergy are regularly referred to by their proper titles. You can include royalty in the above list but since I do not know too many blue bloods, I will move on for now.

A title is an honorific. But what about other professions? Why not Postman Jones? Television Repairman Davidson?

"Hi my name is Collection Agent Jorge."

"Very nice to meet you, I am Ballerina Tom."
