When Maxine and Simon are sitting at the kitchen table talking, Simon's arms are on the table with his hands together when the camera is on Maxine. When the camera is on him, only his left arm is on the table.
When Maxine and Jen are at a restaurant/bar having drinks, Maxine's arms are in different positions when the camera shots go back and forth between them. When the camera is on Jen, Maxine's right arm is on the table with her hand holding her drink. When the camera is on her, both of her arms are down off the table.
When Maxine leaves Jen at the restaurant and goes to her car it is already unlocked. She proceeds to lock and then unlock it to get in.
