A while ago I had a "detatched retina", which was sewn back in place by a very skilled doctor. But for several months, my right eye was extremely sensitive to bright lights, including cameras. During several concerts I was doing then, I had to ask the audience to refrain for snapping pictures. It worked mostly, except for one jerk that kept coming up to the stage and shooting up at me at very close range. Once, when he did that, I blew the song. I knelt down and quietly asked him if he wanted to die now or later. No one else heard me but him. He tip toed out ... to applause. bob
