All others use their Family Name.

Temple Hierarchy
1st: Pope
2nd: High Priest (Even the Pope cannot treat them lightly.)
3rd: Priest
Though lower in rank than the Imperial Family, they are beings that cannot be treated disrespectfully.

Using nicknames is only permitted between lovers and family. Doing so otherwise is a clear insult. Sending items like accessories, dresses, or shoes (or handkerchiefs and watches for men) to someone is a sign of affection. If a young nobleman attaches 'Lady' or 'Mademoiselle' after a request to a young noblewoman, it is effectively a confession. If he adds a complimentary adjective (beautiful, radiant, jewel-like, etc.) before 'Lady' or 'Mademoiselle', it is essentially a public confession.
