Sound

In the first part of the clip no non-diegtic sound is used only dialogue is used. The sound effect of the envolope makes it seem awkward as it's a bussiness transaction, as there is no soundtrack it may make the audience feel slightly awkward as well. The locking of the door is emphasized because its an issue, he feels vulnerable with the door locked. The dialogue is punctured by awkward silences this draws attention to his disability, and they are in an unusual situation for both of them as she perhaps isn't used to doing business with a disabled person and he have never been in that situation before.

There is a diegetic soundtrack of classical music when the dad gets into his van, it is inappropriate to how he is feeling as the music is fast and upbeat whereas he feels anxious and worried about his son. Sound effects are used the pressing of the horn and the moving of the windows and seats emphasizes his nerves.

A sound bridge is used and carries over from the man in the van to the room, non diegetic soundtrack makes you feel sympathy for the the disabled guy, it's mellow music and the dialogue is reflected by the music as he's telling the call girl how she's never been touched. In the last soundtrack a harmonica is used, harmonicas are normally used in the blues which creates a mood of sadness
