Going to the cinema with Down's Syndrome
Ruben is 13 years old, swims for Great Britain, loves to DJ for his mates and also has Down's syndrome.
The genetic condition means he has learning difficulties and looks a bit different to some of his friends.
Around 750 babies in the UK are born with Down's syndrome every year, but it's still unusual to see someone with the condition on TV or in adverts.
Earlier this year, a girl with Down's Syndrome was asked to leave a cinema because she was laughing too loudly.
