Let's write!

Choose two characters, preferably two that know each other in canon. They are together in a private place, such as walking down a forest path, watching TV in a room and no one else is within hearing range, or driving somewhere in a car. One of them takes the opportunity to talk to the other about something private. It could be good (e.g., they want to tell them a good secret like they just bought an engagement ring; they want to compliment the other; they want to share good gossip about someone else) or it could be bad (e.g., they want to chastise them about something bad they did; they want to share bad gossip about someone else) or even neutral (e.g. they want to talk to them about something that's troubling them).

Write that. Bonus points for not choosing the easiest-to-write conversation.
