The idea that bad luck happens when a black cat crosses your path is completely ridiculous. Maybe if the creature trips you up while you walk, but certainly not in any superstitious way. There are no gods or demons that control our destiny, and carrying a packet of salt to throw over your shoulder as a ward against bad luck is absurd.
Yes, yes, that kitten is adorable. No, I don't want to pet her.
However, didn't we pass a trashcan back there? I did take too many salt packets for my fries. I'll just toss out the extras.
