I learned this the hard way about 10 yrs ago, when I took a teenaged son for a mandatory "routine check-up" prior to his playing athletics in high school.
The pediatrician asked my son a number of inappropriate questions, one of which was "does anyone in your family own a gun"?
There was no good reason for the doctor to ask this question. It might have been appropriate if my teenager had presented as possibly suicidal. But my son was (and is) one of the happiest, most well-adjusted persons you could imagine. And we did not live in an area where gun violence is common.
No, this doc considered himself to be acting "in the child's best interest" by asking this question.
My son's answer was "no," which was truthful. But had his answer had been "yes," no doubt the pediatrician would have duly noted this in my son's medical record (with who knows what consequence).
And if my son had answered "none of your business," that response would've been noted in my son's medical records too ... probably labeling him as "belligerent" and "potentially dangerous."
I hope no one in your family was ever examined by that a-hole again.
