I love special days, even superstitious ones like Friday the 13th.
Friday the 13th occurs at least once, but at most three times a year. 2009 has the most Fridays the 13th possible, in the months of February, March and November, according to http://en.wikipedia.org/wiki/Friday_the_13th.
I love words. There are some great ones associated with Friday the 13th, like paraskavedekatriaphobia, friggatriskaidekaphobia (fear of Friday the 13th) and triskaidekaphobia (fear of the number 13). How often can you work that into a conversation?
I'm grateful that each day is different, and some are more special than others.
