The filmmaker of this video shares a transformative moment with a person experiencing homelessness: Walking along a busy street in Edinburgh, my eye caught a sign resting at the feet of a man sitting on the pavement outside a posh hotel. It simply read, 'I am a human being.' It stopped me dead in my tracks. Kneeling down to take a closer look, I struck up a conversation with Sparky. And what started as a quick chat, turned into a few hours together, while Sparky shared his story with us. We need to remember that every person, regardless of their situation, is a human being with dignity, with a name, a story, a family and a history – like all of us. We're all human.
