Superstitions

Are you superstitious? Do you believe in it? Well, there's always a logical explanation to it but still somewhere deep down inside we still believe in it. When i was a kid, i remember my parents told me not to whistle because apparently it is bad. Also, we cannot cut our nails at night (This is believe because those days, we have limited electricity hence we might accidentally cut our finger instead if our nails) Just an assumption.

Also, we were not allowed to cut our hair on Fridays. (This one i think because Friday is a holy day hence no cutting hair) I have had a hair cut on a Friday before.

It is considered a bad omen when a pure black cat pass by your way. I have never experienced anything like that before *touchwood*. However, one of my friend did. Something really bad happened to her after she encountered a black cat pass in front of here. I don't know if this is just a coincidence or this black cat passing in front of you is a bad luck.

Do you have any weird superstitions you are willing to share? Do you believe any of them!? How did it affect you?
