I'm not suspicious at all. I love black cats crossing my path (cuz they're beautiful); I will walk under ladders if it's the shortest route; and I'll also open an umbrella in my house even if people freak over that.
Last year in August, on Friday the 13th, some pretty freaky things happened. Well a hurricane made us evacuate Myrtle Beach on that Friday, then on the way home, the gas tank was punctured by something in the road & gas was going everywhere. Something else happened but I forget now? But all in all it was a crud day, "bad luck abound". But it was just circumstance, not superstition!
So far so good today. The sun's out, it's payday, and I've got a great weekend ahead of me!
