Zac goes to the lake for a swim and to have some time away from his family. He sits down beside the lake, he feels at peace and it’s been a while since he could do that. He breathes in a deep breath of fresh air and smiles to himself, he’s enjoying the solitude. But suddenly something catches his eye, it looks like someone is swimming just a little way off shore. He can see the ripples in the water as they reach for the surface and he can hear splashing sounds. Zac wonders whose out swimming, so he gets up and walks closer.
