Sorry to be late to the party, but WHAT did she put on her Face Book page that generated her father’s response/reaction?
Check the video at the link. He reads her post from hard copy.
He printed it out and read it on his video response.
Mostly...complaining about chores and insulting her parents.
I think the clincher that probably provoked gunfire was when she declared she couldn’t wait until they were too old to wipe their own asses.
