If you don't have children then pretend you do for this. Don't talk as if your explaining it to a regular person. Talk as if you were speaking to a child who has no idea what death is.
Genius!Hubilub said:"Daddy, what is death?"
"Uhm... Go ask your mother sweetheart, daddy is busy... guarding the tv."
You say that, but when you have a traumatized kid on your hands don't run to us. (Not that you would.)Sougo said:"Death is a nap you don't wake up from"
If you believe in it: "Death is a journey to the afterlife."
"Death is the Great Equalizer."
If I have kids, I'm gonna be completely honest with 'em. Tell them things as they are, and as they grow up they'll come to understand them, even if it doesn't make sense to them at the moment.
