It's Friday the 13th. Will that mean anything to you? According to the superstitious, Friday the 13th is bad luck. According to cinemaphiles, Friday the 13th is a series of bad movies. The fear of Friday the 13th is called "paraskevidekatriaphobia." The fear of Friday the 13th movies is called "wussiness." Nah, I'm just kidding. The first one actually wasn't too bad for the genre and the period.
I suggest if you're a teensy bit freaked out over the day, have fun with it instead! Thumb your nose at it! Throw a theme party!
I do things a little more subtly. I just wear a white cable knit sweater and speak in a slightly breathy voice, warning people not to have sex on the beach. (Hey! Serve those as your drinks for that theme party!)
