>>Their behavior took a bizarre turn at a quick restaurant stop when Linda instructed her children to “lie and be completely fake”<<
The same Mrs. Weaver who led them in family prayer in previous episodes?
Yes, Mrs. Weaver, I'm sure God wants you to lie to your fellow man, and purposely tell your children to violate His commandments, all so you can win a million bucks. *rolls eyes*
Did you watch the show, or were you just looking for an opportunity to bash people?
The Weavers were tired, cranky and demoralized. Mom simply suggested that they put on their best face and not let the rest of the teams know that they were weak.
