If you are the suspicious type and believe in superstition, you
may be afraid. This year there are three Fridays that fall on
the 13th of the month. The number three is very significant
because it signifies a completeness. One example is an algebra.
You add a small number three in the top right-hand corner to
make a cube. A cube is perfect and equal on all six sides.
Either good fortune or calamity is identified depending on the
sign and its interpretation of many superstitions. A few common
superstitions here in the Western world could be walking
underneath a ladder to bring calamity or bad luck, having a
black cat cross your path, spilling salt or opening up an
umbrella in a building. All of it could spell doom for you. My
favorite is breaking a mirror. This one supposedly gets you bad
luck for seven years. I wonder who keeps track of those 7
years?! I also wonder if you break more than one mirror, can you
serve concurrent sentences? The fact is a superstition is based
on ignorance and fear of the unknown.
