> Well, quite frankly, Cho didn't see Cedric die. So regardless 
whether or not it has to do with acceptance/understanding of death or 
not, she wouldn't see them.  She experienced death, but didn't see 
it.  Big difference.  I'm sure almost all students have known someone 
who died, a grandparent, someone.  But not near as many have 
witnessed it.

> Now, if there is a discrepancy, I don't think it's necessarily 
Harry's parents death.  He was a baby, couldn't have understood what 
was happening, just that something bad was happening.  For that 
matter, James was apparently in the other room when he died, and that 
leaves Lily.  Harry may well have been crying by this point, as 
babies feed off emotions, and his eyes could have been closed, he 
could've been looking away, anything.

Did HP actually see Cedric die?  I think he saw (in a "dream") the 
old groundskeeper die at the beginning of GoF...
