Other mistake: In the scene where Jenny waits in the car outside an apartment building while David helps a family move into their flat, an older woman looks out of the window of her flat. We see her reflection in the window of the car Jenny waits in. However, the car is standing beyond the corner of the building - there are no windows that could possibly reflect in the car's window.

Continuity mistake: At Jenny's birthday she receives two dictionaries, and one is unopened (the one from the boy). After David arrives with the presents, Jenny says that there's no space on the table, and then we can see both dictionaries are without the wrapping paper.
