Accurately? That’s pretty tricky. How are you measuring this?
I think most people I know are eccentric in some way. That includes me. Really, who is completely “normal, regular, ordinary, customary, conventional” (the antonyms of eccentric)? It’s all a matter of degree.
I don’t watch TV, have no interest in sports (except when the Red Sox are in the World Series), passionately hate to shop, and dislike talking on the telephone. Is that eccentric?
How about my friend in her fifties who is an OCD-compulsive neatnik, wears odd, funky clothes, and takes ballet and piano lessons?
How about another friend who is a clinical therapist by day and a wild denizen of the kinky scene in the dark of night?
I know a woman who wears a hat whenever she goes out, any season, any time of day, and a man who guides every move he makes by consulting his detailed astrological chart. I know a woman who is a man. Several, actually. I have a relative who has a collection of meat grinders in his garage and another who collects stamps, but only those with birds or maps on them. Any eccentricity there? What about the one who died leaving an entire cupboard full of empty glass jelly and mayonnaise and pickle jars, a whole kitchen drawer full of KFC condiments and plastic utensils, a paper sack loaded with quarters, dimes, and nickels in his car, and an envelope containing $1700 under the corner of his bedroom rug? Anything nonstandard or unconventional there?
There may be some normal, regular, ordinary, customary, conventional folks in my sphere of acquaintance, but chances are I’ll never get to know them. The characters are the interesting ones.
