Well, first, the great news: one of the writers in our newly formed little writers group has just got an agent!! And tonight she will be sharing the query letter and sample pages that first snagged her agent's attention. I can't wait to read them.
At our last meeting, one of our members brought a writing prompt from a book on writing song lyrics, and we turned it into a bit of a game. He gave us six prompts, emotions that we were to describe in a short scene, or even a phrase: things like, "I hope I never see you again," or "I think I'm falling in love". The goal was to write the descriptive phrase or short scene without actually saying "I think I'm falling in love" or "I hope I never see you again." Basically, a show-don't-tell exercise.
We had so much fun sharing our results because each person would read what they'd written, and everyone else had to guess which of the six prompts it was written to describe.
Here's some more writing prompts I came across recently that I plan to share at one of our meetings.
