Who knows? Did anyone say that or report that she was "trying to rub their noses in it"?
If so, I missed it. Still, it's possible, and I don't know the answer.
As a kid of 8, one time I walked up to a neighbor man, elderly, who was clipping roses. On a mischievous impulse, I said "BOO!" in a loud voice. He sat down on the ground, got a little bottle out of his pocket, and put a nitro under his tongue...he scolded me--he never had before--and it took a day for me to get over it, talk to my mom, and come back to apologize. He didn't have a heart attack, or even go to the hospital, but he was never welcoming to us kids after that, and I lost a good friend...
