Imagine you live in constant tension. Imagine that there is nowhere safe where you live and you can never peacefully go to sleep. Imagine that tonight, as you are falling asleep, you hear some one knock on your door asking for entry. Imagine that the person you live with, your wife, your flatmate, your mother… gets up and opens the door for them. Imagine the person who enters is another person who lives with you; your son, your flatmate’s girlfriend, your father… and imagine that now, knowing that every one who lives in your house have finally come at the end of today, only now you can know that all your family have lived just one more day.
