Well, I would wager that "Friday The 13" is the direct cause of the North Korean "rocket" not reaching orbit...

They should have waited one more day...

While I do not believe that "jazz" , I do subscribe to GR answer, that NK rocket fiasco is really a lost of face 

I love Friday the 13ths and full moons. The crazies are fun to watch

I also do not walk under ladders, especially not in China, because they're usually leaning it precariously on something while the person is working. I think many people have fallen off of ladders here. I've heard many things in China, like don't eat too many oranges, don't eat eggs with potatoes, drink warm water. All I have to say about that was the warm water wasn't so bad in the winter.

If only Friday 13th was unlucky then all the other days could be lucky days.

I should be so lucky! .....lucky, lucky, lucky.

I can't think of many for me, but I'm from a developed country where I think those ideas kinda died away with the older generations.

I still wouldn't like to walk under a ladder. I do sometimes 'knock on wood'.

I had the most adorable, lovable, loving Black Cat you can imagine.  She was just a Princess.. unique name of 'Blacky',,  or sometimes, 'The Blackness of Doom'!  hehe, such a lovable kitty....

yes its vary bad luck to have intercourse with an odd number of women by the end of the day.

2 gypsies once told me that vary scary.

Yesterday, for the first time in all my time here, I found money on the ground. THRICE. In ONE DAY!

12 yuan richer, suck it, friday the 13th!

no way
