Haaaaaaaaa ,superstitions and their consequences , my opinion on the subject is : if you have superstitions you limit yourself , that is , you can not go under a ladder , if you see a black cat it 's bad luck , my question , you have to go under the ladder to can you get to the designated place, then what do you do, then the black cat, you can't paint it white, you can't remove the skin etc, so it's better to do what you do, laugh at the subject and not mention it to other people, they will call you a bad person and they could even kill you because you generate bad luck :)
