Other mistake: In the beginning, when Julia shows the girls the private gardens, Julia is standing behind them, until suddenly she is standing beside them as she says "Impressed?"

Other mistake: The girls are staying with Julia whose house starts on the first floor, so she has no direct access to the gardens, but when Laura comes back to Julia's place, she enters via the gardens.

Other mistake: As Laura walks into a darkened bedroom, she turns the light switch on. Not only does the room light come on, but also the bedside lamps, just by turning the switch on by the door.

Other mistake: When Rosemary comes back from seeing her old college professor, she comes in from the garden, but Julia's place - this is where Rosemary and Laura are staying - is on the first floor; there's no access to her place from the garden. Rosemary should have gone to the front door, on the street.
Chosen answer: Maybe she thinks she's so old that she'll be back in the mortuary soon, so why go home?
