My Granny always told me that it was bad luck to cut my nails on a Friday or a Sunday and I was always puzzled as to why. I came across this little rhyme in an old book and wonder if she heard it when she was a wee girl -
Of the Cutting of Nails
Cut them on Monday, you cut them for health;
Cut them on Tuesday, you cut them for wealth;
Cut them on Wednesday, you cut them for news;
Cut them on Thursday, a pair of new shoes;
Cut them on Friday, you cut them for sorrow;
Cut them on Saturday, you'll see your true love tomorrow;
Cut them on Sunday, and you will have ill fortune all through the week.
So think about what day it is next time you cut your nails!
