Continuity mistake: After Lydia cleans off the coffee table when she returns and sits down there are only two boxes and a bowl on the coffee table.

Continuity mistake: In the wide shot of the party scene as everyone is running into the house a girl in a bright red sweater and white skirt pulls her mother in the blue dress by the hand.
