Well, be a wise uncle and keep your eyes open. Some children can bounce back with no visible ill effect, and there’s nothing wrong with gently pointing out that it’s not the wisest thing to say something “really stupid” in public (especially if something dangerous is being hinted) as one could get taken seriously in this antsy era we live in. But if the child is obviously bugged, or begins to act bizarrely, for a long time, something more could be afoot here.
