I've not cried at a funeral, well... I tend to be bored to near-tears at them. They're often of the Christian variety in England (or at least the ones I've attended are).
Depends how you look at death, though. I'm one of those who's sad they're gone, but I'm not gonna go nuts. It's the only certainty in life, and you just have to accept it! No amount of crying, screaming, raging, thinking or mourning will bring them back.
I believe it was the Celts who cried at births, and laughed at funerals. Well, that's kinda what I do, except I don't give a rat's behind about births. No one has been born into my immediate family for about 16 years now. Plus, I really don't like kids.
