In the beginning Julia Waters is spreading peanut butter on toast. She then puts the lid back on the jar. The next shot shows her spreading more peanut butter and the jar open.
30 minutes in to the movie, Julia Waters is shown sleeping on the couch, and you can see her right hand (not covered by the blue blanket); when her husband walks in to the room, her hand is covered by the blue blanket, but a second later when he sits down next to her, her right hand is exposed again.
