Wolf: But it does mean we (as Talmudists) have to act like as if it is a distinct possibility.
To what extent? Do you leave the house anytime your teen daughter has a friend over? Does your wife leave when your son has friends over? Do you leave the house whenever your son and daughter-in-law come over for a meal (heck, she’s an actual erva to you, unlike your daughter’s high-school classmate)? If your mother in law were to start telling a story at the Shabbos table, would you not listen? After all, ain apitropus l’arayos, right? We have to treat the situation as there is a distinct possibility that you might have lascivious thoughts, right?
