Those unlucky mornings---eight or nine out of ten unpleasant things in life, for example, being waken up by the alarm clock in the morning, and you are almost late. When you go outside, you find it has been snowing all night and your car is covered with snow. You hurry to wipe off the snow with great effort. After wiping for a long time and finally get it done, you then discover that this car is not yours.
