Imagine a life without television, music or freedom; imagine every minute of your spare time being spent attending church; imagine growing up believing swimming pools, cinemas and dancing were evil. For members of the Exclusive Brethren, a strict religious sect, constraints such as these are normal. No member is allowed to eat in the same room as a 'worldly' person, they are forbidden from owning a pet and they are restricted from socialising with anyone outside of the Exclusive Brethren. Most members are so isolated within the sect that they can't even imagine a life on the outside. But not all members can live such a controlled existence. Once David Tchappat had a taste of the real world as a teenager, there was no going back despite the fact he knew he would be cruelly ostracised from his family, friends and the only life he had known.
