Do we know how old the girl is? I felt her father came across as very immature and petulant, and to do this is undignified and unforgivable. Family problems should stay within the family. It would have been infinitely better for him to have talked to his daughter in a spirit of negotiation about the chores and about her activities on Facebook. Dialogue is the best way. Too much nowadays is in the public eye, it's very distasteful.
