Hello, MtheGM. No, my husband doesn't repeat the last part. For exmaple, if he says:

"mumble mumble mumble the transmission of the blue car"

I have learned to say "What about the blue car?" (not rudely) and he fills me in.

Bill D: I too have noticed the irony of people who defend so-called Black English but don't use it themselves.* Frankly, I think most of Black English is the excited jabber of kids at play. And for various reasons, they are kids who have not had much chance to carry on conversations with interested adults.

I'll tell you a little story. I'm going to volunteer at a local school, and it was the end of our first session together. Nine little black kids were ready for home. They were restless and wouldn't get in line. The boys were joke-kicking and punching each other, and I thought, "Whoo boy, how do we get them to calm down?"

I said "Boys and girls, let's see how many of your names I learned today." It was as if a magic spell had been cast. They froze, whipped around, and nine sets of eyes were riveted upon me. An adult, a nice adult was interested in them, in each one personally! They were eager to tell me their names and their friends' names. Suddenly the mood was changed radically, and we all parted comfortably.

As my friend the educator says, "Any adult who will TALK to them..."

*I have also noticed the irony of academics who write on English usage and defend the split infinitive. Yet you could search the whole book and not find a single infinitive they have split themselves.
