Diane Arbus recorded this over heard conversation at her her group show New Documents in 1967. I wonder what they would have said if they had known the photographer was behind them taking notes!
Man: "There is nothing!"
Woman : "What?"
Man: "Nothing. I could go out and do the same thing."
Woman: Well why don't you?"
Man: "You don't think I could?"
Woman: "I believe you I just want to see you do it."
Man: "Do you think that's good photography?"
