I teach kids laining for their bar mitzvah. I usually teach in the kid’s home, where there are people all around and we are never left alone.
I took on one student last year where the father did not want me to teach in his home. Instead, we had our lessons in a shul. Since (depending on the season) I don’t get out of work until Ma’ariv is over in the shul, very often we are the only ones there.
I have noticed that the father is there for every lesson. He doesn’t participate, of course — he’s off on the other side of the shul learning or talking on the phone, or whatever. But he’s there — and rightly so. *I* know that I would never take advantage of a kid that way — but he doesn’t. I commend him for his vigilance regarding the safety of his son.
