I’m experimenting with very minimal dialogue driven stories. Does this work, or is it too vague?

The lecture hall

The lecture hall filled.

For some, it was their first time.

“I heard the bastard sometimes doesn’t speak at all.”

“Only when he has nothing to say. That’s what I heard.”

“Let’s see what this idiot does.”

“I think he’ll speak today. A lot has happened lately.”

“There’s always a lot happening. Lately.”

The room grew darker. The stage brighter.

“I’m here.”

“He gets straight to the point.”

“I don’t care.”

“I hear.."

“How does he even hear?”

“I don’t care.”

That changed when, in the mirror on stage, a person appeared.

“I hear.

You can ask your questions.”

“He speaks.”
