The author Christopher Morley once had this experience when he went to see a play. He expressed it in this way:
"I went to the theatre with the author of a successful play. He insisted on explaining everything, told me what to watch, the details of the direction. He pointed out the errors of the property person and the foibles of the star. He anticipated all my surprises and ruined the evening."
