     When you are about to do something brave, a cheerful wish of"Good luck!" from a friend can be helpful.

But if you think you need lots of luck, what else might you do?

     In the UK and US there are some strange traditions for bringing yourself a little more good luck. Some are

hundreds of years old and some are much newer.

     Have you heard the saying "When you wish upon a star"? If you are looking up at the sky on a clear night

and you see a sudden flash of light, it is probably a shooting star! Seeing one doesn't happen very often. The

saying goes that if you see one you have been very lucky, and so if you make a wish, it will come true.

     Maybe you have heard of the lucky rabbit's foot. Some people believe that rabbits are lucky animals, so

they carry a part of the rabbit, its foot, for good luck. There are all kinds of strange, unclear rules about

which of the rabbit's feet is the luckiest. It is said that this good luck tradition is the oldest one of all.

However, as the funny saying goes, "Depend on the rabbit's foot if you will, but remember it didn't work

for the rabbit!"

     People in Britain love trees. If it is autumn and leaves are falling from the trees, some people try to catch

the leaves as they fall because they think each leaf they catch will bring them a lucky month in the following

year-they will need to catch 12 falling leaves to have a whole of good luck!
