[Anglika]

A tea-leaf floating on the surface of the tea means a letter is on its way.

The black cat has to walk across a road in front of you to bring bad luck [or good luck - some people prefer this]

A sunny day on your wedding day means a happy marriage.

If you spill salt, you must cast a pinch over your shoulder to get rid of the devil.

If you smash a mirror, you can expect 10 years of bad luck.

If you see a pin and pick it up, you will have good luck.

[These two date to the days when mirrors and pins were rare and expensive.]
