Sad version:
"There were many bitter and painful moments in my life. Countless times, I wished someone could be there with me to get through them. But there was no one.
So I was always alone."
"Hey, hey, you can't see ghosts, okay?
If you could, you'd realize I've been with you all along."
Lighthearted version:
"Shouldn't you be hugging me and asking for comfort now that your parents are dead?"
"It's not the first time my parents have died..."
