Didn't (and never have) cry when my own Mother died so tears for a celebrity are unlikely.
Don't get me wrong. I'm not a cold hearted son of a bitch and I can feel quite emotional when I think about the pointless loss of people like Kirsty Mc Coll or Delores O'Riorden but I lost someone very close to me when I was about 22 ish and pretty much shed a lifetime of tears.
Now I mourn internally and keep all the egood memories alive.
Death is just a process of life and is inevitable so crying buckets is a bit selfish. If someone dies I just celebrate their life within myself and remember all the good emotions that person gave me.
