Her expression was kindly and peaceful. It is said that the eyes are the windows of the soul and from out the abundance of the heart the mouth speaketh! There was the sweetest reflections of peace in the eyes of Mother Therese and since she had learned to keep her interior in order from tender childhood, her deep spirituality could not but reveal itself even in her very countenance and she showed, unknowingly however, that her heart was immersed in Him Whom she loved above all. The refinement of her person, her extreme modesty, and the gentle dignity with which she treated persons and affairs, together with her extraordinary business capacities, gave her all that one would wish to find in a Foundress and an exemplary religious.
The purity of her gaze and the peacefulness which she constantly endeavored to maintain around her, gave a sweet and heavenly expression to her features, which were not beautiful but singularly attractive, so that one felt instinctively drawn to her. Her eyes were grey-blue, rather deep-set and penetrating, but clear and innocent as those of a child. They would sparkle merrily and light up with pleasure, and she could make her nuns laugh gayly too.
She liked her nuns to be always happy, always ready to smile, and if anyone of them would sadden over some trifling occurrences, she would remind her sweetly: "No long faces, Sister. We cannot stand long faces." And it never took long for the culprit to be wreathed in smiles even though her cheeks were still wet with the dew of tears, because Mother Therese never hesitated to portray on her own dear countenance the picture of the "long face" before her.
Great was her delight when with her nuns in recreation, especially on some of the major feasts or on days when her anniversaries were celebrated. On these occasions the Sisters would prepare "surprises" and enact scenes, both pious and amusing, from the lives of the Saints. Mother Therese enjoyed these little festivities and entered into them with a simplicity and a joyfulness that delighted her spiritual children. Unfailingly she had "surprise" for them too on such occasions, when she would herself prepare beforehand some little dainties or extra refreshments, different from the routine food, so that these happy events were sought after and eagerly looked forward to by all with child-like anticipation.
