Let's write!

Today's challenge: Use dialogue, and dialogue only, to paint the picture of where the characters are and what's going on.

It might help to write this in form of an audio play. Imagine two characters in an audio-format story, where the only thing the audience hears is the dialogue. Write their dialogue, whatever it is they're talking about, such that the listener gets a clear picture of the setting and situation without the characters sounding unnatural or forced.

As an example, the following dialogue sounds unnatural:

Tom: There's Sarah, just coming in the restaurant door, right by the maitre d'.
Mary: She looks really good in her red dress.

No one talks like that. Something more natural might be:

Tom: Ah, there's Sarah, finally. Now maybe we can get to order. I've been waiting long enough for this lobster thermidor.
Mary: Hey, do you think she's lost a few? That red dress looks really good on her!
