Sound

The absence of a sound track for the majority of the clip, creates awkward silences between dialogue.  The dialogue is very weak and quiet during this scene.  This adds to the awkwardness of the situation.  Also, a lot of the actor's lines are unfinished, they stutter and pause between words, highlighting their discomford and anxiety.

The diegetic sound effects, of the girl fiddling with the locks on the door, are amplified to draw the audience's attention to the boy's anxiousness.  Her dialogue during this scene also contains awkward pauses and unfinished sentences to empahsises her awkwardness in the situation.

The scene of the father sitting in his car maintains an ambient sound of street noises that you would expect to hear during the day.  The short diegetic soundtrack is asynchronous to the mood of the scene, which adds to the fathers discomfort and draws attetion to the discontinuity of the scene.  Diegetic sound effects of the car window, the seat sliding and the car horn are clearly heard to exaggerate the silences and to emphasise the father's anxiety.

A sound bridge of a non-diegetic soundtrack is used between the scenes in the two locations.  The soundtrack is composed using a harmonica, commonly used in blues and for sad moments.  This choice of soundtrack makes the audience feel pity for the boy, because of his disabiltiy and the awkwardness of the situation.
