The trouble children find with strangers is that it can be impossible to look at someone and know their intent.
Not every person they meet is a lurking danger, but do we want them taking the chance and engaging them.
In short the answer is a firm NO.
On the same token we want our kids to polite and courteous.
How do we teach them in a way that will stick with them, that talking to strangers can be dangerous?
I have tackled this tough issue, and believe I have a story that can be used as a tool to help push the notion home to them.
In my story ( Stranger days) Sammy the shark has his first encounter with a stranger, learn along with Sammy as he discovers the hidden dangers of strangers.
