Just that. My 13 year old plays a lot of sport and it would be useful for her to be able to wear disposables every so often. We went somewhere in the summer for her to have a go but she couldn't do it - and the woman showing her was not very patient. DD's a bit of an anxious type when being observed so if there is an opticians that's known for handling young people better, I'd rather taker her there. I realise it might differ from branch to branch but would still love to hear of other's experiences.
