Note 1 — ENGLISH COURT FESTIVITIES
Reading edition
Footnote 1:
(return)
[The rule, more correctly stated, is, that "sir" is never used except to indicate a difference of age or position so great as to forbid familiarity or to be incompatible with social equality. It may be employed by the elder in addressing the younger, and by the superior in addressing the inferior, as well as vice versa. Hence the saying, in English society, that only princes and servants are spoken to as "sir."]
