unaffectedness การใช้

Photographer David LaChapelle recently shot the actress for Details magazine and was impressed by her friendliness and unaffectedness.
"The unaffectedness and evident sincerity of the artists is one of the chief charms of their work.
You were struck by her behavior, particularly by the extraordinary sincerity and unaffectedness of her relations with others ."
