Academy Award Winning Movie Trailer (2011), by Youtubers BriTANick (original video title Trailer For Every Oscar-Winning Movie Ever [2010])
It's _not_ a play or a piece for theatre, but a spoof film trailer. But the theme of the dialogue is so _exactly_ what you describe that I'm posting it as an answer anyway. For example:
> B: Friendly concern that something may be missing from your life.
> A: Confidence that nothing is missing in my life.
> B: Interrupted statement about -
> A: Reassurance that my good fortune will not waver.
> _[Cut to A in a dark room holding a half-empty bottle. A knock at the door.]_
Later:
> B: Specific outlining of your major character flaws.
> A: Overreaction! _[slamming B against the wall]_
> C _[unseen]_ : Friendly black optimistic advice.
> D _[sobbing]_ : Passionate plea! Whispered repetition.
