One for sorrow,

Two for mirth (or joy, or luck, in some versions),

Three for a wedding,

four for a birth, (or a death, in some versions),

(Three and four are sometimes for "a girl" and "a boy," respectively.)

So many options.

The old nursery rhyme goes on:

Five for silver,

Six for gold,

Seven for a secret never to be told.

Eight for a wish,

Nine for a kiss,

Ten a surprise you should be careful not to miss,

Eleven for health,

Twelve for wealth,

Thirteen, beware. It's the devil himself.

Look for the signs.
