heh, most of this is probably common sense, but then again it's not like anybody ever spelled it out.
Most times I hear of stories, its always in a sensationalistic way, like, okay the person who met the celbrity was blown away, but the way they tell the story they make you think like the celebrity is a leprechaun and if you catch them they will give you their pot of gold, or 3 wishes etc.
One reason I'm curious is because a fairly well known saxophonist on the jam circuit was signing autographs after the show, so I got in line and when it was my turn I handed him the CD's of the recording he just made from the show that night (which is awesome btw, there's nothing like a goody bag from the show you just saw! Venues be advised)
So when it was my turn I handed him my CD's and I just noticed a certain stillness about him. Like he was degaussed or something, and the power of that stillness was fairly intimidating. A certain aura of degaussed ness. I've noticed that magnetism, and from not really meeting a whole lot of important people trying to subdue that magnetization in advance.
