Like "So very sorry to hear your sister's friend succumbed to the ignorance and laziness of the medical profession. But before we get too hard on the Drs, it must be said that sometimes folks who are told "You have diabetes" stop listening and that is all they hear. Human beings are complex creatures physically and emotionally. Since your sister wasn't there when her friend was Dx'd she doesn't know what was said. Dr could have told her all the "right stuff" but patient was not ready to hear it. Yes she could have done what you & I did and research, but unfortunately for her she did not for whatever reason. I suspect your sister may appreciate you a bit better now. Praying for your improving health and blessings to you and yours James "
