When you're a writer, it's all well and good to ask for help. But this is beginning to get into the realm of asking people to write your story for you.

One thing about being a writer is, going outside and into the great, big, wide world. Even teenagers can go out into the world; it can be perfectly safe to do so. You're writing about a family. What do families do together? Where do they go? Go and watch!
