Anata Nude - Flywheelsites News
Using either (name)-san, or anata is the most safe/inoffensive way of referring to second person in japanese. However, it is considered rude if used to refer to parents, relatives, or teachers. The pronoun anata is the supposed neutral way to refer to someone whose name you're not aware of, and it's ok to use it to a stranger if you can't think of any other way to phrase the thing you want to.
