Good for dad! Honestly, no matter what the dad chose to do would have been criticized. He did the best he could on the spur of the moment. I do not believe it was poor parenting. I believe it was a good choice to fight her with the technology she uses to demean he and his wife. Dad proved he could be tech savvy, as well. Children get away with far too much. I was afraid of my parents until they passed away and I was in my 50s. Parents are not our friends, but our mentors. Children, who do not respect their parents, need to have their attitudes adjusted. Could he have done it differently? Maybe. But I applaud that he chose to do something that his daughter understood. Maybe she will think twice about her big mouth and public demeaning of the two people who do everything for her.
