My parents have some new neighbours. They are German (the neighbours not my parents that is). My parents being the kind people they are have gone over to make sure they know which bin to put out when etc. So last week they all went out for a meal. The husband of this couple works for a construction firm. He announced that they had had to evacuate the site the other day because they had found a bomb. My mother, without a moments hesitation, turned to him and said "one of yours or one of ours?" My father is still cringing now.
