There is a contra dance caller who has invented a dance called
Triskadeccaphobia!!

Fear Triskadeccaphobia!!

watch out tomorrow...

Sorcah..is that the reason you crush egg shells? (witches boats?)

What about a black cat crossing your path? broken Mirrors?

and a black crow flying over you or to your left has some

significance, as i recall from Carlos Castaneda,

in the Yaqui Way of Knowledge.
