I'm not going to try and make you, or try and force you to get it but maybe it would help to put out some thoughts as to why I'm "grieving" (or, listening to his music all day. That's about it.) for someone I've never met. Bowie is one of those people that has had a profound impact and influence on a lot of peoples lives. He managed to become a mega-star while still being this meld of experimental and pop sensibilities and worked to bridge the gap between the two. His music is his legacy, and for a lot of people he's the reason they started playing an instrument or become deeply invested in music. Plus he was a total weirdo and who doesn't love that. Death isn't about personally knowing a person. It's about the impact someone had on you in your life and development.
