From A to B: A Play in One Scene

I overheard this conversation today. What I didn't hear was how it began, so we may never know what important point was never made.

A: It does what? It whats the problems of development?

B: Adumbrates. It adumbrates the problems of development.

A: Adumbrates?

B: Yes, adumbrates. It means to...

A: I know what it means. But who says that? Who says "adumbrate"?

B: I do. I say "adumbrate."

A: No one says "adumbrate."

Not sure why this struck my fancy. But it certainly must be in the running for the much-coveted "Conversation That Employs 'Adumbrate' Most Frequently."

I with A--no one says (or should say) "adumbrate."
