I really need some Cage wisdom on this one:

Suppose that you're acquainted with someone. Not a close friend, but a friend of friends that you're likely to encounter again in future. In your limited encounters with them, this person seems perfectly nice and normal. Then, by complete fluke, you happen upon some totally unexpected information about them...

Namely that their family was a world-leading producer of animal porn, directed by their father and starring their mother, sister, and a stepmother who is described as "The reigning queen of bestiality". At first you found this information totally unbelievable, but there is indisputable proof in the form of boxcovers in which you can identify their relatives from their facebook photos.

You can't see any evidence of this person being involved in the bestiality, although they have directed a few human based porn movies and played an administrative role in the "family business".

So in this situation, which of course is totally theoretical and not real in any way, how would you handle the next time you see them, knowing that their mother starred in "Fat Dog Fucker" and "Granny's Dog Orgy", while their sister was in "Dog Sperm Bitch" and "Kinky Pony Girls", all directed by their father? Would you mention it at all or keep quiet? And if you decided not to mention it, how would you summon the mental discipline required to keep a straight face?

All opinions gratefully received...
