Much of the skill is in the way things are said.
"your dead father, his name wasn't John was it?"
"yes it was." "I thought so."
"no it wasn't" "I thought not"
I once saw Sally Morgan on tv. She waved her hand from her neck to her waist and said "he died form something in this area." Very good. That includes heart, lungs, kidneys, liver, stomach, in fact about 95% of everything people die from!
But the women said "no, he had leg ulcer that went septic!" So Sally paused and then, waving her hand aver her midriff said "but he had trouble breathing, at the end." And the woman was ecstatic. "Yes he did, he really did!"
Well of course he had trouble breathing, he was dying ffs! Trouble breathing is a pretty standard symptom of death!
Honestly, you couldn't make it up. And the audience, sadly 95% women, were lapping up the drivel. Embarrassing.
