“People stare at the floor. Even to look at a homeless person is to sign a contract with them. I dabbled with joining the Samaritans once. The supervisor had been homeless for three years. I remember him saying that the worst thing was the invisibility. That and not being able to go anywhere where nobody else could go. Imagine that, owning nothing with a lock, except a toilet cubicle in King’s Cross Station, with a junkie on one side and a pair of cottagers on the other.”
