I just watched an episode of Girls and then an episode of Shameless. In both programs, some undesirable guy entered a lady’s dwelling unexpectedly (Adam in Hannah’s apartment; Frank in Sheila’s house). When asked how they managed to do it, in each case the guy said that he “still” had a key. Presumably Hannah and Sheila gave the keys to Adam and Frank some time in a previous season.
Television writers, please place a moratorium on this “I still had a key” trope for at least five years.
