In a "jump scare" scene, Andie is peeking through the Venetian blinds in the kitchen when they suddenly, and completely, fall down onto the kitchen floor. She leaves the room and then re-enters the kitchen a short time later. The blinds are back up in their proper position and remain there for the rest of the film.
When Andie returns to the apartment after her trip to the park, she hangs her keys on a key hook by the front door as she comes in. Later, she's seen standing by the door and the keys have disappeared.
