I felt a tinge of sadness when Aaliyah, B.I.G., McDuffie and Whitney Houston passed. Tupac notsomuch. I was a fan, but his death seemed inevitable due to his lifestyle.
Usually though, other people's sadness confuses me - especially when it's older, retired celebrities like Andy Griffith or that guy from Welcome Back Cotter. Much of the Michael Jackson "love" seemed disingenuous, since he was so ridiculed before he died.
