I never heard of sauce calld gravy until the Sopranos.
I can certainly relate to the list and everyone's experiences , especially Signor Cardi's
As for sauce vs. gravy. I've heard this stupid argument my whole life, and I'll say this: I've heard them both, so I guess it depends upon where you grew up. In the New York City area, you probably heard "gravy" more often. I know I did, and I grew up on 187th Street, in the heart of the Belmont section of the Bronx.
