Just discovered this on the writers digest website and wanted to share it. I am going to write something with it. I just think it's a neat prompt! Feel free to post your scene in the comments.
Good luck and have fun!
Not Your Real MotherMother's Day is over and you've just finished a nice dinner with your mom when you receive a phone call. An unfamiliar female voice is on the other end and says, "Stop celebrating with her! I'm your real mother." Write this scene.
