Continuity mistake: When Peggy is leaving for her guitar recital, she is getting in the car and is wearing a pink sleeved shirt. Then there is a quick shot from behind the car, when Peggy is getting into her car, but her shirt is now a sleeveless green one.
Continuity mistake: After the Mother's day recital the Hills are driving home in the truck. When they show Bobby saying, "Uh I didn't take my medicine" you can see the seat backing behind him is a dark green color. You can also see the framing and bars around the back window is also dark green. After showing Peggy and Hank again, it goes to another close up of Bobby and the seat backing is now light blue like the front seat backing. The framing and bars around the back window have also changed to a silver color.
