The "curl up in a ball/protect the neck" is just for dogs. Currently for people their are two rules:
1. If we are with her DD can be polite to strangers but not overly friendly. If we vouch for the stranger then she can trust them fully.
2. If someone does something inappropriate say "No", get away, then tell someone (parent/teacher...)

We keep close tabs on her, but you never know... The world just seems really nuts right now. <img src="/images/graemlins/frown.gif" alt="" />
