There are many superstitions(迷信) in Britain, but one of the most widelyheld is that it is unlucky to walk under a ladder—even if it means stepping off the pavement into a busy street!

①Walking under a ladder

If you must walk under a ladder you can avoid bad luck by crossing your fingers and keeping them crossed until you've seen a dog. Alternatively, you must lick your finger and make a cross on the toe of your shoe, and not look again at the shoe until the mark has dried.

②Umbrella

Another common superstition is that it is unlucky to open an umbrella in the house—it will either bring misfortune to the person that opened it or to the household. The superstition could date from the old time when its purpose was to act as a sunshade. If opened indoors, it might be considered to be an attack on the sun. Anyone opening an umbrella indoors in fine weather is unpopular, as it inevitably brings rain!
