Mr. X steps into his sitting room and finds his son watching porn.
Without distracting him, he sits by his son in silence -- fir a while.
"K, do you know about heaven and hell?"
"What about them?"
"Good people who love God, and do his will, will inherit heaven. The bad will go to hell."
"What are some of the actions that can lead one to hell?"
"Fornication, killing, stealing, masturbation, pornography, e-er-r-mm-m..."
Mr. X gets out of the room.
