I certainly find this true in my case. For example: I am attempting to write a sequel to my "The Southern Belle Breakfast Club" book and I need a new character to bring in for a possible love connection. I find myself looking at different people in hopes to catch their individual actions, personality or moods swings. I carry a writing pad and pen around with me to jot anything down that might be interesting. I am very careful not to let people see me stare - after all mama raised us to know that staring is rude.
