Imagine your house is burning, and it burns right to the ground. You lose everything and you are very frightened and you have nowhere to go. But you know you have to leave – and far across the water – over on the very distant horizon you can see another house and you can see people beckoning to you to come over – and so you make the journey – a long, often arduous and dangerous journey – and you finally get to the house across the water – and someone steps out of the house and they take your name and other details and then ask you to wait. And you wait – and wait – and wait on the veranda. You can hear people in the house moving around talking and laughing, you can smell the food etc. But you are just left to wait – with no idea if and when someone will invite you in.
