Today's writing prompt is to stretch your dialogue skills.
Write a scene using dialogue only between a husband and wife. There will be no dialogue tags (he said, she said) to start with, just strict dialogue. Make sure the "voices" are inherently male and female, and don't forget to insert conflict into their conversation.
Once you're done, insert the dialogue tags and other descriptions of the scene . . . with the female on your "male voice" and a male on your "female voice." This should make for an interesting gender role reversal exchange.
