how does the sound help to construct the representation of disability.

There's a complete absence of soundtracks for the first 3 minutes of the sequence, and that help in creating the mood and emphasising the awkwardness of every single scene and the ambience of the flat is very quiet!
- Dialogue: the actors' dialogue is a succession of unfinished sentence like "shall i... erm please... dad...'' that helps creating some kind of tension as no one really knows what to say or how to anything view the awkwardness of the situation.
- The very distinct sound the closing and the girl locking it also helps in occasioning the boy's anxiousness as he feels vulnerable being alone in that room the girl.
-The sound that comes out of the radio was deliberately chosen to create some kind of in-synchronisation with the atmosphere or the dad's mood to highlight his anxiousness.
-a sound bridge starts from the end of dad's scene on the car to the call girl and the boy in the room, this helps in creating some kind of sadness to make the audience feel kind of pity towards the boy. And we notice that it's the harmonica playing, and usually instruments such as harmonica or violent are used to create a sad atmosphere.
