Without wishing to sound mean, it is bad enough that people mourn celebs that they have never met and do not know. Are we now expected to do the same when the children of the celebrities die.
I can understand a bit of empathy toward Nick Cave who is still alive, who lost his son tragically. You feel for the man and his loss, even though you had no idea he had a son until he was killed.
But when the celeb is dead, in the case of Frost, then I do not really feel any grief. It is someone I did not know existed has gone. I do not know his family or friends, so it affects me no more than a news item where people had died in an earthquake of bomb.
We all see people we care about die throught our lifetimes and it is usually not a nice period. So I will not be joining in any faux mourning.
