Just because Prince William has grown up as a member of the Royal Family doesn't mean he hasn't made a royal faux pas on occasion and he's spoken publicly about one of these "awkward" mistakes before. It happened during his first time attending one of the annual Diplomatic Corps receptions and the late Queen Elizabeth's reaction was rather surprising.
These events bring together ambassadors, diplomats and high commissioners from all over the world. The prospect of meeting so many important people all at once would be daunting for anyone, so it's understandable that Prince William finds them a "diplomatic minefield".
