Well, it's today. I am not a supertitious guy, so I never really believe in the so called bad luck, bad day, or full of mishap day. I mean, I can't count how many times I've "hit" this Friday the 13th, and I never really had any unfortunate experience with the date.
I guess, this "day" only affects those who really believes it's a bad day. I guess people celebrating their birthday today should best be postponing it. But hey, if you're like me, then this day is just like any other day.
In any case, whether you believe it or not, I hope you guys never had any bad luck this day. If you believe in it, then take the necessary precautions. If you don't, then continue to have fun =)
