Sometimes it’s easier to see than explain:
Here’s a typical conversation at a social gathering, grocery store, or school fundraiser:
Then they hold eye contact, waiting for me to ask them what it’s about. I smile and leave the silence for just a teeny bit longer than a normal conversation would have because I’m a jerk.
Then I finally ask “What kind of book?”
Usually they’re taken aback because it’s not what they expected to be asked. They say something like “to teach kids about fire safety” or “it’s about the first day of school.”
I say, “No, what I meant is, is it a picture book? A Young adult?”
“It’s for kids,” they’ll say.
“But which kids?”
“All kinds of kids.”
I’m not getting through. I take a deep breath. “Let me ask this way: Who is your reader? What age?”
