The Duke and Duchess of Cambridge (Will and Kate) are coming to Canada this week.
There is certain etiquette–things you should and should not do–in dealing with, and speaking to, royalty.
Etiquette is a type of “manners.”
It can also be called “protocol” in the case of the royals.
For instance, protocol demands that Will and Kate be addressed as “Your Royal Highness,” followed by “sir” or “ma’am.”
Men can then bow from the neck and ladies can curtsy to the royals.
Over the years there have been plenty of “breaches of protocol” — mistakes that people have made around royalty.
