For me, everything about Friday the 13th is all so superstitious to me. It's all old school. Now, deaths are caused by crimes and not by a vampire, howling fox or any haunted or possessed characters, nor by a mysterious death. But I know that there's no harm in taking precautions.
For me, Friday the 13th is almost equivalent to September 11th - a day and date to be scared of. What's the difference anyway?
