Why has this phrase been attributed to Queen Marie Antoinette, when there is no record of her saying it?

Apparently because Jean-Jacques Rousseau, in his autobiography, Confessions, wrote this: “I recalled the stopgap solution of a great princess who was told that the peasants had no bread, and who responded: “Let them eat brioche.” Wikipedia

People assumed.

 

Consider the infinite capacity for words to lead to misunderstandings, and write a 150 word autobiography in which you insinuate that someone you know said something they didn’t.

Enjoy.
