In case you are worried about class being on Friday the 13, just pretend we are in another country/culture. As a website on Friday the 13th trivia notes, “Friday the 13th is not universally seen as a day of misery. For example, in Italy, Friday the 17th and not Friday the 13th is considered to be a day that brings bad luck. In fact, the number 13 is thought to be a lucky number! In many Spanish speaking countries and in Greece, Tuesday the 13th is seen as a day of misfortune.”.
