How Shirley Booth described Hazel to TV Guide

[Smilings]

Shirley Booth said Hazel is "a good human soul, honest and likable. The most important thing is that she's capable of honest anger. A good strong, purging emotion - without being nasty about it. Instead she substitutes a sense of humor - which is really a sense of good taste - and hence manages to get away with saying the things most of us wish we'd said."

from page 182 of Love is the Reason for it All, the Shirley Booth story.
