About 3/4 of the way into the movie. The Mom is coming home and pulls into her driveway. As she enters the drive, there is a car already there. When she gets out of her car it is the only one in the drive.
About mid-way through the movie the family was in the back yard burring the dog and Olive wasn't wearing her cast. Her arm was broken in a previous scene when she fell or was pushed off the play equipment.
Emily is watching as Tamara's ex-husband comes to see Tamara. He pulls his car straight into the driveway facing the house. When Emily goes out to take out the garbage a short while later she sees the car leaving and it is pulling straight out of the driveway facing the road.
