"A Festivus for the rest of us!" This is the unofficial motto of this non-commercial alternative to Christmas. Celebrated on December 23, Festivus was popularised by the TV show "Seinfeld," although it was actually invented by the family of one of the series" writers. This celebration centres around the unadorned aluminium Festivus pole. After dinner, the traditional Festivus "airing of grievances" gets underway. This consists of telling friends and family the ways they"ve disappointed you over the year. According to some mental health professionals, this tradition could be good for people"s mental well-being, providing some much-needed catharsis at what can be a difficult time of year for many people.
