Hess compares Ono's behavior to a performance piece, but there's a more likely, if prosaic explanation: Ono was from a family of wealthy Japanese aristocrats. The Beatles were working-class musicians. In the world that Yoko came from, you didn't worry about the feelings of the people you outranked. Why should she care if she was irritating the fuck out of everybody?
...when she graduated she was admitted to Gakushuin University as its first female student in philosophy.She left after two semesters. She said the university made her feel “like a domesticated animal being fed information.” This proved to be a lifelong allergy to anything organized or institutional. “I don’t believe in collectivism in art nor in having one direction in anything,” she later wrote. A classmate offered a different perspective: “She never felt happy unless she was treated like a queen.”
And the article points out that Ono, unlike the Beatles, was very well-educated (Ringo never even finished high school) and could read music. More evidence that the real issue in the Get Back recording sessions was that Ono felt she outranked the Beatles. And since they were used to being treated like gods by that point, you could see why they would resent that.
Don't feel alone. Having time to yourself is a blessing. Think of all the great books that could never have been written except for all that lonelines.
