While In the Mood is a major change of focus for the playwright who earlier wrote Secrets of a Soccer Mom, thereby helping launch a national catchphrase, it is still firmly about real people, families and relationships. Clark has an ear for, well, normal life, and the big hearts that often go with it. Her plays celebrate regular people facing and solving the ordinary problems that life throws at them.
Another of her popular early plays is Southern Comforts about a mismatched elderly couple in search of a meaningful relationship. Kathleen Clark is a mom, a mother, and a role model for normalcy. Her plays are written with love, understanding and warmth, reflecting her outlook on life. She is no kid playwright purging their frustrations with life. She deals with them.
