I recently finished editing a friend's novel and a big piece of feedback I kept giving was, "show don't tell" in moments where character dialogue would go further than narrator summarization.
I thought about this in relation to the children's poetry I write. One thing that can irk me in writing for kids (especially in poetry it seems) is that the message is constantly told to young readers, as if they can't piece it together from something being shown to them.
Lessons are written bluntly and morals directly stated rather than inferred as they often must be in fairytales and fables. I think these shortcuts are for good reason though and not a result of lazy writing. There seems to be a desire to hook readers as much as possible, as if pieces must be clickbait themselves. So, by creating a quick setting or scene and then explaining the importance, there is a feeling that what’s needed to be said has been said and hopefully the child understands. Maybe a piece of this is true, but I think it’s when challenged to find meaning that the messages sticks. And this doesn’t have to be riddle or anything difficult!
For example, I could have written a piece saying that "everyone is in important" or "everyone has a story," but instead I wrote "Bill Ordinary," creating a character and scenario for readers to infer this message from and make their own reading. Rather than being a didactic adult about it, I want the audience to reflect on what they consider ordinary and what they consider remarkable in their own lives and just saying those things or directly asking them to reflect wouldn’t have the same effect.
Trust your readers to be intuitive, curious, and smart. Show them a message in action rather than stating it directly!
