That's like saying of all the inane posts on this forum why did you take objection to this one?
Honestly though, someone died whilst I was writing this sentence, I don't care because I don't know who it is, and if through the course of the coming days I don't get the bad news that it was someone that I cared about I'll continue to not care. the only reason that anyone "cares" about this guy dying is that he was on TV, his part made people laugh and brought joy to them...
My favourite trigger scene is when he gets an award from the council after he keeps the same broom for years, then later reveals that it's only have 9 new heads and 14 new handles (something like that anyway)
It has to be the characters, we don't know the actors, nine times out of ten they are not our friends. we believe we know then from years of watching a character that they projected on screen.
