Real people tend to be boring most of the time. They sit in traffic to and from work; they hunker behind desks day after day or drive the same delivery route yet again; they eat dinner with their family and spend the holidays with their relatives. The big excitement comes on the weekend when they go out to a movie or to a concert or party.
Most real people wouldn’t make good characters in books. Rather than attempting to make characters real, authors would be wise to listen to Ms. Brontë and make them realistic instead.
