My dd is 10 and she truly believes.
Last year parents talked to their children in her class so as not to ruin it for her, nothing to do with me I should say, some friends told me about it later.
The problem is everyone in her year are non believers and everyone knows that my dd believes. She is not a naive girl and people find it astonishing.
The problem is I keep imagining Sue from the middle who gives a presentation on unicorns to the whole class, then being furious with her parents for not telling her they didn't exist.
Is it time to tell her?
