Comment by TheScorgon on How I Became an SSS Rank Delivery Hunter - Chapter 27

@TheScorgon The title "Sir" carries a certain amount of social weight and is a formal way to acknowledge a person's status as a knight.

@LunarSilvio Don't care I wan't my "ma'am"s when it's a woman and my "sir"s when it's a man.

@TheScorgon It is essentially a military thing. You will still refer to a female military officer by 'sir' nowadays. But for a knight, it is a title, like Lord or Lady.

@LunarSilvio Even for a knight it's a military thing and not a title.
