According to Cosmopolitan, January 6th is National Affair Day aka the supposed day when people are most likely to start an affair. This is based on the fact that IllicitEncounters.com, a British affair website sees the sharpest spike in people signing up. They also note that almost 6% of Britain's married population will be on this site by the end of January. Time to tell your boyfriend to watch his ass as apparently January is National Douchebag Month. I guess it's only logical that the only way to follow the most wonderful time of the year is the most adulterous time of the year.
