i just thought it was clever because you dont really realise how much all your senses do for you. i think it is poignant aswell how she is struggling as to whether she actually wants to hear or not!! excellant drama on so many levels. i think it is also good how they have shown her as a normal teenager- as she is, i dont mean offence by this, what i mean is in programes people with disablities, it is all about that, but this also shows that they are normal teenagers too. Drinking, partying, smoking etc. Hope that makes sense.
