A snippet from Invisible by Cecily Anne Paterson: 'It’s hard to make friends when you’re always new. It’s even harder to make friends when they notice you wear a hearing aid. My voice is getting better, but it’s not always clear and I have to work hard to make sure that I’m listening to people and that they can understand me. That’s another thing that frustrates my mum. I don’t really work at it. Maybe sometimes people try a little bit to be friendly but I don’t always hear them and it seems that not many people try twice.'
