ENTERTAINMENT WEEKLY: Curtis, lets start with the origins of this project.

What was the appeal of writing a short story to be exclusively listened to?

Its honest, emotionally intimate, and easy to visualize.

The mercurial nature of our memories and how they define our internal experience is immediate.

The story, listened to, is about an hour.

SITTENFELD:What isnt the optimal setting?!

This is a funny, relatable exploration of marriage.

What does it say about the institution?

LANE:Long-term relationships have moments of regret or disappointment that are benchmark.

Theres a lot of humor and heart, so it requires some range.

It was exciting to hear my words in her elegant, versatile voice.
