Death

Holly: "When Granny-Barbara died, did she go in one of those... those.... What are they called? They are like big triangles with a square at the bottom...?"
Daddy: "What - a pyramid?!"
Holly: "Yes! - A PYRAMID!"
Daddy: "Well, no, she wasn't an ancient Egyptian queen."
Holly: "But that's what they did with dead people a long time ago!"

Thus begins a long discussion about digging holes to put dead people in, graveyards, gravestones, and some worried questions about "what makes people dead, Daddy?" and finally "what makes people be alive, Daddy?"
