I envy anyone who has met Kate Bush. She's my idol, but I can completely understand why she keeps her distance. She's had a few stalkers go after her in her time, poor woman. I don't think I'd actually want to approach her if I saw her in public, knowing just how much she values her privacy and normality.
My cousin used to live practically next door to her. She never met her or even saw her the whole time she lived there.
