Well, I know it was yesterday, but I had technical problems and a little bit sad to not publish this long word that I found that explains fear of this day, it is paraskevidekatriaphobia, the longest word i know until now...
I'm not superstitious but it's a very intersting theme, so, let's not take risks for our own sake :) And face every 13th friday and his neighbours days with a smile on our faces.
