Alemão:
Es gibt einigen Aberglauben rund um Freitag den 13…
Aber es gibt keinen Grund diesen Tag zu fürchten, in einigen Kulturen ist die 13 eine Glückszahl!
Der amerikanische Börsenspekulant Thomas W. Lawson verbreitete durch seinen Roman 1907 das negative Image dieses Datums.
-> Trivia englisch
Diese Angst hat sogar einen Namen bekommen: Paraskavedekatriaphobie
Ich halte nichts von Aberglauben, das bringt Unglück!
Wenn ich schon mal da bin, lasst uns doch treffen ?
Ich hoffe wir kollidieren nicht mit einer anderen Veranstaltung?
Inglês:
There is a lot of superstition around Friday 13th…
There is no need to fear this day, in some countries the 13 is considered a lucky number!
The american plunger Thomas W. Lawson dispersed the negative image trough his novel in 1907.

While there is evidence of both Friday and the number 13 being considered unlucky in some countries, there is no record of the two items being referred to as especially unlucky in conjunction before the 19th century.
Early tall-building designers, fearing a fire on the 13th floor, or fearing tenants' superstitions about the rumor, decided to omit having a 13th floor listed on their elevator numbering.
This practice became commonplace, and eventually found its way into American mainstream culture and building design, with the 15 floor immediately following the 12.
These Americans again...
Buildings in some parts of China avoid the 4, 14, 24, etc. floors, because of the similarity between the pronunciation of the word "four" and "death" in Chinese.
Another variant found in Vietnam is naming floors 13 and 14 as floors "12A" and "12B" respectively.
In South Korea, buildings tend to include the 4 floor in spite of similar pronunciation issues in the Korean language, though some newer buildings may substitute the letter F in the place of the number 4.

This fear even has a name: paraskevidekatriaphobia
I don´t believe in superstition, that´s bad luck!
While I am here, let us meet.
Hopefully there will be no other event today?
