Why did Jacqueline Kennedy, the wife of President John F. Kennedy, evaluate Queen Elizabeth as a "mediocre middle-aged woman"?

The two men have been at odds because of some things, especially when the president's wife attacked the queen with words.

The Queen hosted a state banquet in Buckingham Palace in honor of President Kennedy and his wife. That year, the Queen was 35 years old and the First Lady Jacqueline Kennedy was 32 years old. They are similar in age and status, but when they meet, the tide is really dark. When the president and his wife left England, Queen Elizabeth heard Jacqueline comment on her rude language. Jacqueline once said that the Queen is such a mediocre and boring middle-aged woman.

In fact, before this happened, the Queen of England and the First Lady had a holiday. Before President Kennedy came to Britain, there was a contradiction between the two sides when drawing up the guest list for dinner. Jacqueline suggested that she wanted to invite her sister and brother-in-law. Jacqueline's sister married for the second time, and for the third time, she married Prince Lasswell of Poland, holding the title of princess living in England. But at that time, there was a rule in the British royal family that divorced people could not participate because the British royal family was conservative.

The Queen of England disapproved of Jacqueline's sister and brother-in-law attending the party. Of course, Jacqueline would not agree with the Queen of England, but in the end, because the dinner was not a formal state banquet, the Queen of England agreed to let his sister attend, but she did not give up easily, so she took a little revenge on Jacqueline. Jacqueline also asked to meet the Queen's sister and aunt, both of whom are famous fashionistas. The Queen of England did not invite the two members of the royal family to attend.

The Queen of England and the First Lady had a quarrel because of the guests attending the dinner party, but the Queen of England kept her manners when receiving Jacqueline.
