A stern teacher of etiquette knows the rules of proper behavior, and she keeps her students in line. But young Jeffrey (who seems to be closely related to playwright Jeffrey Hatcher) has a few ideas of his own — including some insight about his teacher that might help him earn a never-before-achieved perfect grade on the final exam. Playing the leading role in Ensemble Theatre Cincinnati’s regional premiere of MrsCopenhagen for ETC, with Hodges in a central role. By the way, while behavior is expected to be beyond reproach, ETC warns that due to strong language, Mrs. Mannerly is recommended for mature audiences. Through Oct. 28. $38-$42.
