Oh, you can't be. I never would have been able to do the things I did if I was pushy, aggressive, in their face, or whatever. And you get to know these people and your limitations. You know what you can ask them to do, or if something is happening in front of you that you can photograph or not. For instance, there is a shot in the book of Dylan the first time he met Bruce Springsteen. It was on the Rolling Thunder tour, and I was in the dressing room with Bob, and there was a knock on the door: "Bruce Springsteen is here." He said, "Well bring him in." And they had never met before. I took maybe nine or ten frames, I knew I had the image, I knew they wanted to be alone, so I left.
