Errors made by characters (possibly deliberate errors by the filmmakers): Harold tells Ana that she can deduct the bread she gives away to the homeless as charitable contributions on her tax return, which is not true. In order to qualify as a charitable contribution, the property (in this case, the bread) must be given to a qualified charitable organization and be properly documented. Simply giving away food to the homeless is not enough, as there would be no way to prove that she actually gave the bread away.
