Nuala MacDonald tells Rachel Burden how she made her village in the Highlands become autism-friendly. She has encouraged businesses to have a quiet hour where no music is played, or have heat maps on display which show busy areas that can be noisy.

Café Hope is our virtual Radio 4 coffee shop, where guests pop in for a brew and a chat to tell us what they're doing to make things better in big and small ways. Think of us as sitting in your local café , cooking up plans, hearing the gossip, and celebrating the people making the world a better place.

We're all about trying to make change. It might be a transformational project that helps an entire community, or it might be about trying to make one life a little bit easier. And the key here is in the trying. This is real life. Not everything works, and there are struggles along the way. But it's always worth a go.
