I don't grieve... generally.
The only death I've ever been really, honestly sad about is that of Gawain... my feline companion from the age of 2 to the age of 14.
No other death has ever really phased me, nor given me any sort of emotional thoughts.
My father's death was somewhat of an inconvenience in some respect, though I got a couple of thousand pounds from him dying so it wasn't a total loss.
I guess I'm just the classic definition of a cold, heartless bastard.... and somewhat proud of it, in as much as one can be proud unemotionally.
