Aleteia, Philip Kosloski: Therese Martin was a stubborn and childish little girl. Her mother Zelie was terribly worried about her and her future. She wrote in a letter, “As for [Therese], one cannot tell how she will turn out, she is so young and heedless … her stubbornness is almost unconquerable. When she has said no, nothing will make her change; one could leave her all day in the cellar without getting her to say yes. She would sooner sleep there.”
Something had to change. If it didn’t, God only knows what would have happened. More here.
